A certain substance has a heat of vaporization of 62.41 kJ/mol. At what Kelvin temperature will the vapor pressure be 5.00 times higher than it was at 317 K?

Solutions

Expert Solution

This problem is solved using the Clausius-Clapeyron equation. In order to solve it, please follow the next steps:

Step 1. Get to know your equation.

Step 2. Prepare your data.

= 62.41 kJ/mol = 62410 J/mol

R = 8.314 J/(mol K)

T₁ = 317 K

T₂ = ?

P₁ = P₁

P₂ = 5 P₁

Step 3. Re arrange the equation

Step 4. Solve for T₂
