For the parallel reaction A → B and A → C, of rate constants k1 and k2 respectively, both reactions of order 1, the rate expression is given as ____(a) (-rA) = k1CA + k2CA(b) (-rA) = k1CA – k2CA(c) (-rA) = k2CA(d) (-rA) = k1CA |

Answer» Correct option is (a) (-rA) = k1CA + k2CA For explanation I would say: For a zero order reaction, (frac{-dC_A}{dt}) = k1CA + k2CA A forms two products: B and C. The concentration of A decreases as the reaction progresses. |
