Initially, a gas of diatomic molecules is contained in a cylinder of volume V1 at a pressure P1 and temperature 250 K. Assuming that 25% of the molecules get dissociated causing a change in the number of moles. The pressure of the resulting gas at temperature 2000 K, when contained in a volume 2V1 is given by P2. The ratio P2 / P1 is ________.
So, ideal gas equation will be
……. (1)
So, ideal gas equation will be
……. (2)
total number of moles = (2 × 0.25 × no. of moles) + (0.75 × no. of moles)
or
So, the correct answer is 5.
