Mount everest rises to a height of 8,850 m above sea level. at a base camp on the mountain the atmospheric pressure is measured to be 296.0 mm hg. at what temperature (in °c) will water boil at base camp ? the vapor pressure of water at 373 k is 760.0 mm hg. (δh°vap for h2o = 40.7 kj/mol and r = 8.314 j/mol k)

74.86°C

Explanation:

P₂ = Vapour pressure of water at sea level = 760 mmHg

P₁ = Pressure at base camp = 296 mmHg

T₂ = Temperature of water = 373 K

ΔH°vap for H2O = 40.7 kJ/mol = 40700 J/mol

R = Gas constant = 8.314 J/mol K

From Claussius Clapeyron equation

T₁ = 347.996 K = 74.86°C

∴Water will boil at 74.86°C

correct it is c.) b b
