Question

4. The Presence of a Cafays 2. What is the overall order of the reaction with respect to A and B for a reaction that obeys the rate law: Rate = k[A]2 [B]2 ? The overall or der of the reachun S afourth-order reachón 3. It is found for the reaction A + B → C that doubling the concentration of A doubles the rate of reaction and doubling the concentration of B quadruples the reaction rate. a. Write the rate law or this reaction. b. What is the overall reaction order of the reaction.
Please help with number 2 & 3 with step by step to get the right answer

Answer 1

2.

Rate = k [A]² [B]²

Overall order of the reaction is 2+2 =4.

3.

A + B   $\rightarrow$ C

Rate = k [A]^m [B]ⁿ

Now,

Doubling the [A] , the rate of raction doubles. So, A is of first order, which is m=1.

Doubling the [B] , the rate of raction quadruples. So, B is second order, which is n=2.

(a). Rate law of the reaction is

Rate = k [A] [B]²

(b). Overall order of the reaction is 1+2 = 3.
