An irreversible gas phase reaction 2P→4Q+R is conducted in an isothermal and isobaric batch reactor. Assume ideal gas behavior. The feed is an equimolar mixture of the reactant P and inert gas. After complete conversion of P, the fraction change in volume is ________(round off to 2 decimal places).

Options

none

Answer

0.75

Solution

ξa=ya/deltaaξ_a = y_a/delta{}_a
..
ξa=/frac32/times0.5ξ_a = /frac{3}{2} /times 0.5
ξa=0.75ξ_a = 0.75
Hence, the correct answer is 0.75
