For the reaction A + 3B -> C, select the correct statement.
- d[C]/dt = -d[A]/dt
- 3 d[C]/dt = -d[B]/dt
- Rate law must be r = k[A][B]³
- Units for rate of reaction are independent of order of reaction
Correct answer: d[C]/dt = -d[A]/dt
Solution
Since A and C have equal coefficients, the rate of formation of C equals the rate of disappearance of A; the rate law cannot be assumed from stoichiometry.
