1. The rate (velocity) of a reaction is-
a. The free energy dissimilarity between products and reactants
b. The time it takes the reacting system to reach equilibrium
c. The dissimilarity in product concentration divided by time
d. The dissimilarity between the rate constants of the forward and the reverse reactions
e. All of the above
2. The reaction A + B C + D is an example of-
a. Zero order reaction
b. First-order reaction
c. Second-order reaction
d. Fourth-order reaction
3. For a reaction A + B C + D, the forward rate constant is K1 also the reverse rate constant is K-1. The rate (velocity) of the forward reaction is:
a. (K1)/(K-1)
b. (K1)/[A][B]
c. [C][D]/[A][B]
d. (K1)(K-1)[A][B]
e. (K1)[A][B]
