Find the boiling point temperature at 760 torr of an isomer of octane, c8h18, if its enthalpy of vaporization is 38,210 j mol-1 and its vapor pressure at 110.0°c is 638.43 torr.

According to Clausius-Clayperon equation,

is the vapor pressure at boiling point = 760 torr

is the vapor pressure at T_{2} =638.43 torr

Temperature

Δ

Plugging in the values, we get

ln

Therefore, the boiling point of octane = 389 K - 273 =

particle   p is an electron and particle q is a neutron
