If the vapor pressure of ethanol (CH3CH2OH) at 25 ∘C is 60.6 mmHg, calculate the value of Kp

Homework Answers

Answer #1

ethanol (l) <--------------------> ethanol (g)

                                               60.6 mmHg

at equilibrium ethanol vapour is formed 60.6 mmHg. so Kp depends on only vapour but not on liquid ethanol

Kp = Pethanol

Kp = 60.6
