Passage / Comprehension

For the following reaction, $2 A (g) + B (g) \to C (g)$ , the rate of reaction is $- \frac{d [ B ]}{d t} = k [A]$ . In an initial reaction mixture, the partial pressures of A and B are $2 a t m$ and $1 a t m$ respectively at $300 K$ . At $100 sec$ , the total pressure of the reaction mixture becomes $2 a t m$ at $300 K$ . ( $ln 2 = 0.693$ )

Rate of reaction at 200 sec is

Options:

Answer:

Solution:

Rate of reaction $= k [A]$

$ROR = \frac{In 2}{200} \times \frac{0.5}{0.082 \times 300} = 7.04 \times 1 0^{- 5} M / sec$
