Solution

The correct option is A $P_{t} = P_{0} (1 + \frac{t}{273}) (t =^{o} C)$
$I f v o l u m e i s c o n s t a n t \frac{P 1}{T 1} = \frac{P 2}{T 2} \frac{P_{0}}{T_{0}} = \frac{P}{T} G i v e n T_{0} = S T P = 273 K P = \frac{P_{0}}{T_{0}} \times T (T = D e g r e e C e l s i u s) P = \frac{P_{O} (273 + T)}{273} P = P_{0} (1 + \frac{T}{273})$

For a first order reaction $A (g) \to 2 B (g) + C (g)$ at constant volume and 300 K, the total pressure at the beginning (t=0) and time t are $P_{o}$ and $P_{t}$ respectively. Initially, only $A$ is present with concentration $[A]_{o}$ and $t_{1 / 2}$ is the time required for the partial pressure of $A$ to reach a third of its initial value. The correct options are:
(Assume that all these gases behave as ideal gaes)
