Question

Acetone has a vapour pressure of 53.3 kPa at 39.5 °C and 202.6 kPa at 78.6 °C.
From the above data, obtain an equation to correlate the vapour pressure of
acetone. (The equation should be in the form In(P)= -A/T + Co where P, is in kPa
units. Find numerical values for A and Co)
A= 5756 K, Co = 17.989
A= 4756 K, Co = 16.989
A= 3756 K, Co = 15.989
A= 2756 K, Co = 14.989
