Answer» Correct answer is (c) (frac{-r_A}{a})=(frac{-r_B}{b}) ≤ (frac{r_R}{r} ) The explanation is: The rates of degradation of reactants and formation of product are related to each other as (frac{-r_A}{a} = frac{-r_B}{b} = frac{r_R}{r} ), where a, b and c denote the stoichiometry. The rate of disappearance of any reactant in turn is the rate of formation of products. |
