and

{A} \xrightarrow{K_2} {S},

the rate of disappearance of reactant '

{A}

' is

View answer and explanation

Correct option: B

\left(K_1+K_2\right) C_{{A}}

Option B (

(K_1+K_2) C_{{A}}

) is correct because the rate of disappearance of A is the sum of the rates of the two parallel reactions.
