Question

Given the equation A + 2B --> P

1) According to the law of mass action, the reaction will exhibit?

a) zero order kinetics

b) second order kinetics

c) Third order kinetics

d) First order kinetics

2) If reactant B is in much greater excess than reactant A, the reaction will exhibit..

a) zero order kinetics

b) second order kinetics

c) Third order kinetics

d) First order kinetics

3) If reactant A is in much greater excess than reactant B, the reaction will exhibit...

a) zero order kinetics

b) second order kinetics

c) Third order kinetics

d) First order kinetics

Explanation / Answer

A+2B = P

law of mas action, states that th reat depend son th ecoefficients of reagents that is

RATE = K* A^1 *B^2 = 1+2 = 3 ; that is thir order

2)

if B >> A; then this turns to RATE = k*[B]^2; second order

3)

of A >> B ; this turns to RATE = k*[A]^1 first order
