Chemical Engineering :: Stoichiometry
- The heat capacity of a solid compound is calculated from the atomic heat capacities of its constituent elements with the help of the
- Equal masses of CH₄ and H₂ are mixed in an empty container. The partial pressure of hydrogen in this container expressed as the fraction of total pressure is
- The activity co-efficient of a solution, which accounts for the departure of liquid phase from ideal solution behaviour
- An ideal gas can be liquified, because
- The value of the gas-law constant 'R' is 1.987
- Volume occupied by one gm mole of a gas at S.T.P. is
- The density of a liquid is 1500 kg/m³. Its value in gin/litre will be equal to
- One mole of methane undergoes complete combustion in a stoichiometric amount of air. The reaction proceeds as CH₄ + 2O₂ → CO₂ + 2H₂O. Both the reactants and products are in gas phase. ΔH°298 = - 730 kJ/mole of methane. Mole fraction of water vapour in the product gases is about
- The boiling points for pure water and pure toluene are 100°C and 110.6°C respectively. Toluene and water are completely immiscible in each other. A well agitated equimolar mixture of toluene and water are prepared. If, at a total pressure of one standard atm. exerted by the vapours of water and toluene, the mole fraction of water Xw in the vapour phase satisfies
