1) For the reaction A + 2B → products , doubling the concentration of A doubles the rate of the reaction. Doubling the concentration of both reactants increases the rate of reaction by a factor of eight. The reaction is

Select one:

a. second order in A and first order in B

b. first order in A and second order in B

c. first order in A and first order in B

d. second order in A and second order in B



2) For a reaction A(g) 2B(g) + C(g), 7 moles of A are allowed to come to equilibrium in a closed container. At equilibrium, how much of A and B are present if 2 moles of C is formed?

Select one:

a. 3 moles of A and 4 moles of B

b. 5 moles of A and 4 moles of B

c. 0 moles of A and 4 moles of B

d. 5 moles of A and 2 moles of B
