Choose the substance with the lowest vapor pressure at a given temperature. CaF2 o Ar BF3 OPF5 O CO2 At what temperature will a reaction be spontaneous? AH = +22.2 kJ/mol and AS = +81.1 J/K-mol and assume both do not vary with temperature. at T< 298 K at T< 274 K at T> 274K O at all temperatures O at T > 298 K Express the equilibrium constant for the following reaction. 3 P4(s) + 15 O2(8) = 3...
How is vapor pressure related to temperature? What happens to the vapor pressure of a substance when the temperature is increased? Decreased? Check all that apply. The relationship between vapor pressure and temperature is not linear, but rather, it is exponential. The relationship between vapor pressure and temperature is linear. The vapor pressure of a liquid decreases with increasing temperature. The vapor pressure of a liquid increases with increasing temperature.
