The vapor pressure of ethanol is 115 torr at 34.9 oC and ΔHvap of ethanol is 38.6 kJ/mol, use this information and the Clausius-Clapeyron equation (shown below) to calculate the temperature in oC at which the vapor pressure is 760 torr (remember to convert temperatures to K in the equation (K = oC + 273). R = 8.314 J/mol·K. ( Please show each step, step BY step) I am having difficult with finding T2

The vapor pressure of ethanol is 1.00 x 102 mmHg at 34.90oC. What is its vapor pressure at 51.73 oC? (ΔHvap for ethanol is 39.3 Kj/mol.) Given the vapor pressure at one temperature, P1, we can calculate the vapor pressure at a second temperature, P2. In (P1/P2) = ΔHvap/R (1/T2 - 1/T1) Where, ΔHvap for ethanol must have the units of J/mol. R = 8.314 J/K.mol .. The temperatures must be in Kelvins. Solve for P2, What is the vapor...
