Problem

Initially a gas of diatomic molecules is contained in a cylinder of volume

V_1

at a pressure

P_1

and temperature

250 \text{ K}

. Assuming that 25% of the molecules get dissociated causing a change in number of moles. The pressure of the resulting gas at temperature

2000 \text{ K}

, when contained in a volume

2V_1

is given by

P_2

. The ratio

P_2/P_1

is _____.
