Consider a first order gas phase decomposition reaction given below A

1.	Consider a first order gas phase decomposition reaction given below A(g)→B(g)+C(g) The initial prssure of the system before decomposition of A was pi. After lapse of time 't' total pressure of the system increased by x units and became 'pt'. The rate constant k for the reaction is given as ...... . (a)k=2.303tlogpipi−x(b)k=2.303tlogpi2pi−pt(c)k=2.303tlogpi2pi+pt(d)k=2.303tlogpipi−x

Consider a first order gas phase decomposition reaction given below

$A (g) \to B (g) + C (g)$ The initial prssure of the system before decomposition of A was $p_{i}$ . After lapse of time 't' total pressure of the system increased by x units and became ' $p_{t}$ '. The rate constant k for the reaction is given as ...... .

$(a) k = \frac{2.303}{t} l o g \frac{p_{i}}{p_{i} - x} (b) k = \frac{2.303}{t} l o g \frac{p_{i}}{2 p_{i} - p_{t}} (c) k = \frac{2.303}{t} l o g \frac{p_{i}}{2 p_{i} + p_{t}} (d) k = \frac{2.303}{t} l o g \frac{p_{i}}{p_{i} - x}$
