Question

Two parallel first-order liquid phase reactions $A \xrightarrow{k_1} B$ and $A \xrightarrow{k_2} C$ are carried out in a well-mixed isothermal batch reactor. The initial concentration of A in the reactor is $1$ kmol m$^{-3}$, while that of B and C is zero. After 2 hours, the concentration of A reduces to half its initial value, and the concentration of B is twice that of C. The rate constants $k_1$ and $k_2$, in h$^{-1}$, are, respectively,

• A. 0.40, 0.20
• B. 0.23, 0.12
• C. 0.50, 0.25
• D. 0.36, 0.18

Answer 1

Answer: (B)

0.23, 0.12

Answer 2

The correct option is (B) :0.23, 0.12
