Question
For irreversible elementary reactions in parallel $A\overset{\quad K_{1}\quad}{\rightarrow}R\text{ and }A\overset{\quad K_{2}\quad}{\rightarrow}S$, the rate of disappearance of reactant ‘A’ is
Options
A.(k1 − k2)CA
B.(k1 + k2)CA
C.1/2 (k1 + k2)CA
D.k1CA
Solution
$r_{A} = \left( - \frac{d\lbrack A\rbrack}{dt} \right)_{1} + \left( - \frac{d\lbrack A\rbrack}{dt} \right)_{2} = K_{1}\lbrack A\rbrack + K_{2}\lbrack A\rbrack = \left( K_{1} + K_{2} \right).\lbrack A\rbrack$
