Question

1.) If a random reaction A + B Products is first order with respect to A and second with respect to B, how is the rate impacted when the concentration of A and B are doubled?

A) It increases by a factor of 2

B) It increases by a factor of 4

C) It increases by a factor of 8

D) It decreases by a factor of 4

E) Not enough information to determine

2.) You have the following reaction:

NO₂ (g) + CO (g) ⟶ NO (g) + CO₂ (g)

The rate constant (k) at 701 K is 2.57 M^-1s^-1. If the activation energy is 150 kJ/mol, what is k at 895 K? R = 8.314 J/(mol*K)

A) 680 M^-1s^-1

B) 443 M^-1s^-1
C) 2.58 M^-1s^-1

D) 0.950 M^-1s^-1

E) 6.52 M^-1s^-1
