YOUR ANSWER : ?
The molar composition of a gas is 10% H₂, 10% O₂, 30% CO₂ and balance H₂O. If 50% H₂O condenses, the final mole percent of H₂ in the gas on a dry basis will be be
YOUR ANSWER : ?
At 100°C, water and methylcyclohexane both have vapour pressures of 1 atm. Also at 100°C, the latent heats of vaporisation of these compounds are 40.63 kJ/mole for water and 31.55 kJ/mole for methylcyclohexane. The vapour pressure of water at 150°C is 4.69 atm. At 150°C, the vapour pressure of methylcyclohexane would be expected to be
