Answer:

Option (2)

Explanation:

Equation : A ----» 2B + C

Intial pressure = Po , Pressure at time t = Pt

Initial pressure. At time t

A. Po. Po - x

B. 0. 2x

C. 0. x

Total pressure Pt = Po - x + 2x + x

Pt = Po + 2x

x = (Pt - Po)/2

Then rate constant of reaction would be

k = \frac{2.303}{t} log( \frac{ po}{po \: - \: x} )

k = \frac{2.303}{t} log( \frac{ po}{po \: - \: ( \frac{pt - po}{2}) } )

k = \frac{2.303}{t} log( \frac{ 2po}{3po \: - \: pt} )

Hope it helps.
