Question

( k=frac{2 cdot 303 log left[frac{p_{i}}{p_{t}}right]}{t}=frac{2 cdot 303}{40 times 60} log left[frac{200}{200-150}right. )
( k=5.77 times 10^{-4} mathrm{sec}^{-1} )
Hence option (1) is correst-

# Sliyle Cruce The decomposition of azo methane, at certain temperature according to the equation (CH3)2N29- CH() - N2() is a first order reaction. After 40 minutes from the start, the total pressure developed is found to be 350 mm Hg in place of initial pressure 200 mm Hg of azo methane. The value of rate constant kis: (log 2 = 0.30) 2.88x10-* sec B 1.25x10 sec C 5.77x10 sec ? D 4.606x10-sec-
