Answer : The rate order of reaction is, second order reaction.
Explanation :
Rate of reaction : It is defined as the rate of change in concentration of reactant or product with respect to time.
Order of reaction : It is defined as the sum of the exponents or powers to which the molar concentration in the rate law equation are raised to express the observed rate of reaction.
As per question the reaction will be :
![A+B\rightarrow C+D](https://tex.z-dn.net/?f=A%2BB%5Crightarrow%20C%2BD)
The given rate expression is,
![Rate=k[A][B]](https://tex.z-dn.net/?f=Rate%3Dk%5BA%5D%5BB%5D)
From this expression we conclude that the power of concentration of reactant A and B are 1, 1.
The sum of power of concentration of reactant A and B = 1 + 1 = 2
That means it is a second order reaction.
Hence, the rate order of reaction is, second order reaction.
Answer:
E) None of these
Explanation:
For this question, we must remember the definition of a <u>chiral carbon</u>. In the chiral carbons, we have <u>four different groups</u> around the carbon.
So, an achiral molecule would be a molecule that does not have chiral carbons. That is, in an achiral molecule in all carbons we have at least one repeating group.
In all the molecules, which we have in the question, we have absolute configuration. That is, we have chiral carbons. In molecule A we have two chiral carbons (R and R), in molecule b we have two chiral carbons (R and S), in molecule c we have two chiral carbons (S and S) and in molecule d we have two chiral carbons (R and S). <u>Therefore in all molecules, we have chiral carbons.
</u>
Now, if we analyze molecules a and c, we have a <u>plane of symmetry</u>. If we have a plane of symmetry, even though there are chiral carbons, there will be <u>no optical activity</u>. That is, these molecules do not have the ability to deflect polarized light despite having chiral carbons. Therefore molecules a and c are <u>meso compounds</u>.
<em>But optical activity is not related to chirality.</em>

Answer: 11 Electrons
Explanation: This is because a neutral atom has the same number of protons and electrons.
The hydrogenation of ethyl cinnamate will result to an ester which can be a racemic mixture of products or just a meso compound depending on the structure of the ethyl cinnamate (cis or trans). The ester will produce a frequency of C=O stretch of <span>1750 - 1735 (s.</span>
Answer:
heres the answer: Daily changes in the weather are due to winds and storms. Seasonal changes are due to the Earth revolving around the sun, differences in temperature create a restless movement of air and water in great swirling currents to distribute heat energy from the Sun across the planet.

if this is wrong i am genuinely sorry.
