Snow and ice sublime spontaneously when the partialpressure of water vapor is below the equilibrium vaporpressure of ice. At 0°C the vapor pressure of ice is0.0060 atm (the triple-point pressure of water). Takingthe enthalpy of sublimation of ice to be 50.0 kJ mol-1,calculate the partial pressure of water vapor belowwhich ice will sublime spontaneously at-15°C.

Snow and ice sublime spontaneously when the partial
pressure of water vapor is below the equilibrium vapor
pressure of ice. At 0°C the vapor pressure of ice is
0.0060 atm (the triple-point pressure of water). Taking
the enthalpy of sublimation of ice to be 50.0 kJ mol-1,
calculate the partial pressure of water vapor below
which ice will sublime spontaneously at-15°C.
