Question

Consider this reaction.

A+B⟶AB

Which three of these factors will not increase the rate of the reaction ?

a. decreasing the kinetic energy

b. increasing the temperature

c. increasing the concentration of A

d. adding a catalyst

e. lowering the energy of activation (𝐸a)

f. increasing the concentration of AB

g. decreasing the concentration of B

Answer 1

a. decreasing the kinetic energy - this would decrease the rate of reaction, not increase it.

c. increasing the concentration of A - normally this would increase rate unless the rxn is ZERO order in A

f. increasing the concentration of AB - this would not increase the rate of reaction

g. decreasing the concentration of B - this would decrease the rate of reaction unless it is ZERO order in B
