The Moon turns on its axis and orbits earth in the same amount of time
The reaction is given as follows:
![cyclopropane (g)\rightarrow propene (g)](https://tex.z-dn.net/?f=cyclopropane%20%28g%29%5Crightarrow%20propene%20%28g%29)
The plot of ln[cyclopropane] verses t is linear with slope
.
The plot for ln[cyclopropane] verses t is linear for first order reaction (as in the diagram attached). The integrated rate law equation is as follows:
![[A]=[A_{0}]e^{-kt}](https://tex.z-dn.net/?f=%5BA%5D%3D%5BA_%7B0%7D%5De%5E%7B-kt%7D)
Here, k is rate constant, t is time of the reaction,
is concentration of reactant at time t and
is initial concentration of reactant.
Taking ln both sides,
![ln[A]=ln[A_{0}]-kt](https://tex.z-dn.net/?f=ln%5BA%5D%3Dln%5BA_%7B0%7D%5D-kt)
Comparing with equation for linear graph, y=mx+c
Thus, slope =-k
Or,
.
Therefore, order of the reaction is first and rate constant is
.
Answer:
Maple syrup will have the higher temperature.
Explanation:
- Adding CaCl₂ to water and maple syrup will rise the temperature of both of them.
Specific heat of maple syrup = 2.01 J/g.°C
.
Specific heat of water = 4.18 J/g.°C.
- Which means that the energy needed to rise the temperature by 1.0 °C of 1.0 g of water (4.18 J) is twice as that needed to rise the temperature by 1.0 °C of 1.0 g of water (2.01 J).
- So, the temperature of maple syrup will be higher than that of water when CaCl₂ is added to both of them.
Answer:
1. First
2. Third
3. Fourth
4.remain the same as
Explanation:
Given the reaction equation;
Rate= k[A] [B]^3
We can see that the order of reaction is first order with respect to reactant A and third order with respect to reactant B. This gives an overall fourth order reaction.
If the concentration of A is doubled and that of B is halved. The rate of reaction remains the same.
Answer:
Electronegativity is the strength an atom has to attract a bonding pair of electrons to itself. When a chlorine atom covalently bonds to another chlorine atom, the shared electron pair is shared equally. The electron density that comprises the covalent bond is located halfway between the two atoms.
Hope this helps!
