1. The rate (velocity) of a reaction is-
a. The free energy dissimilarity between products and reactantsb. The time it takes the reacting system to reach equilibriumc. The dissimilarity in product concentration divided by timed. The dissimilarity between the rate constants of the forward and the reverse reactionse. All of the above
2. The reaction A + B C + D is an example of-
a. Zero order reactionb. First-order reactionc. Second-order reactiond. 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]
