Chemical Engineering - Stoichiometry
Exercise : Stoichiometry - Section 3
21.
Internal energy is independent of the __________ for an ideal gas.
22.
__________ fuels require the maximum percentage of 'excess air' for complete combustion.
23.
Pick out the wrong statement:
Clausius-Clapeyron equation relates the latent heat of vaporisation to the slope of the vapor pressure curve.
At the boiling point of liquid at the prevailing total pressure, saturated absolute humidity is infinite.
Percentage saturation and relative saturation are numerically equal for an unsaturated vapor gas mixture.
Clapeyron equation is given by,
; where, P = vapor pressure, T = absolute temperature, λ = latent heat of vaporisation, VG and VL = volumes of gas and liquid respectively.
; where, P = vapor pressure, T = absolute temperature, λ = latent heat of vaporisation, VG and VL = volumes of gas and liquid respectively.24.
__________ equation relates latent heat and boiling point.
25.
At higher temperature, molal heat capacities of most of the gases (at constant pressure) __________ with increase in temperature.
