Answer :
The rate law expression for zero order reaction will be:
![Rate=k[A]^0](https://tex.z-dn.net/?f=Rate%3Dk%5BA%5D%5E0)
The rate law expression for first order reaction will be:
![Rate=k[A]^1](https://tex.z-dn.net/?f=Rate%3Dk%5BA%5D%5E1)
The rate law expression for second order reaction will be:
![Rate=k[A]^2](https://tex.z-dn.net/?f=Rate%3Dk%5BA%5D%5E2)
Zero order reaction : There is no affect on the rate law.
First order reaction : The rate law becomes doubled.
Second order reaction : The rate law becomes quadrupled.
Explanation :
Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
The given reaction is:
The rate law expression for zero order reaction will be:
The rate law expression for first order reaction will be:
The rate law expression for second order reaction will be:
Now we have to determine that if doubling of the concentration of A then the rate of reaction will be:
As we know that the zero order reaction does not depend on the concentration of reactant. So, there is no affect on the rate law.
As we know that the first order reaction depend on the concentration of reactant. So, the rate law becomes doubled.
As we know that the second order reaction depend on the concentration of reactant. So, the rate law becomes quadrupled.
<h3>Answer:</h3>
Number of Protons = 6
Number of Electrons = 6
Number of Neutrons = 7
<h3>Explanation:</h3>
Number of Protons:
As the number of protons present in the nucleus are equal to the atomic number therefore, using periodic table one can easily find out the atomic number of C atom. Hence, C is present in group 14 and period 2 and having an atomic number of 6. Therefore, number of protons in C atom are 6.
Number of Electrons:
As shown in statement, C is not carrying any type of charge. It means this atom is neutral in nature. Which means, it is carrying the same number of electrons as the number of protons in order to give a neutral atom. Therefore, it contains 6 electrons.
Number of Neutrons:
Number of neutrons can be calculated using following formula,
No. of Neutrons = Atomic Mass - Number of Protons
As,
Atomic Mass = 13
So,
No. of Neutrons = 13 - 6
No. of Neutrons = 7
This is because aluminium forms an ionic bond with chlorine while nitrogen bonds covalently with chlorine.
Atoms are made of three types of sub atomic particles, they are the electrons, neutrons and protons.
Electrons are negatively charged and they are orbiting around the nucleus in energy shells. Protons are positively charged , neutrons are neutral and have no charge, both neutrons and protons are located in the nucleus.
In atoms the atomic number is the number of protons the atom consists of and mass number is the sum of protons and neutrons in the nucleus.
In a neutral atom, the number of electrons and protons are equal, this means that the number of negative charges and positive charges are equal.
lets take Cl as an example. Its atomic number is 17.
number of protons and charge - +17
number of electrons with charge - -17
overall chage sum of the charges = + 17 -17 = 0
therefore no charge, hence its neutral.
isotopes are the same element having the same atomic number but different mass numbers.
³⁵Cl -protons - 17 electrons - 17 neutrons 18 neutrons
³⁷Cl - protons - 17 electrons - 17 neutrons 20 neutrons
Both are same element with same number of protons and electrons, however the number of neutrons are different.
Since protons + neutrons = mass of the atom
and when the number of neutrons change - mass of atoms too change
hence, ³⁵Cl has a mass of 35 and ³⁷Cl has a mass of 37. both of these are called isotopes
Ions are atoms which have either gained an electron or lost an electron and are charged.
metals such as K(atomic number - 19) have one valence electron in the outer shell, to gain the configuration of a complete octet, K needs to give out this one electron.
then number of electrons 19-1 = -18
number of protons = +19
overall charge = +1
K is one electron less therefore becomes positively charged and called a cation- K⁺
if we take Cl, atomic number - 17
Cl has 7 valence electrons, to gain a complete octet in the outer shell it needs to have 8 electrons, therefore it needs one more electron to complete the outer shell.
Therefore it gains one electron,
number of electrons 17+1 = -18
number of protons = 17
overall charge = -1
with an extra electron, Cl becomes negatively charged, a negative ion called anion - Cl⁻
