Product description

Calculate the change in entropy when 2 mol of methanol is heated from 25 to 100 ° C, if the specific heat of vaporization of CH3OH is 1100.4 J / g, the boiling point is 64.7 ° C, and the molar heat capacity of liquid methanol is СР (l) = 81.56 J / mol ∙ hail and methanol vapors

СР (g) = 15.28 105.2 ∙ 10 -3T - 31.04 ∙ 〖10〗 ^ (- 6) T ^ 2 J / mol ∙ deg.
