JEE · NEET Previous Year Question

$For a reaction scheme A k_{1} B k_{2} C, if the rate of formation of B is set to be zero then the concentration of B is given by :$

Topic: JEE PYQ

Answer: D. Full step-by-step solution below.

A $(k_{1} - k_{2}) (A)$
B $k_{1} k_{2} (A)$
C $(k_{1} + k_{2}) (A)$
D $(\frac{k _{1}}{k _{2}}) (A)$

Correct answer: D

Solution

(d) A k_{1} B k_{2} C \frac{d ( B )}{dt} = k_{1} (A) - k_{2} (B) = 0 (B) = \frac{k _{1} ( A )}{k _{2}}
