Question 1

Hydrogen peroxide (H2O2) decomposes according to the equation
         H2O2(l) → H2O(l) + 1/2O2(g).
Calculate Kp for this reaction at 25°C.  (ΔH° = –98.2 kJ/mol, ΔS° =  70.1 J/K·mol)

Question 2

In the gas phase, formic acid forms a dimmer, 2HCOOH(g) (HCOOH)2(g).  For this reaction, ΔH° = –60.1 kJ/mol and ΔG° = –13.9 kJ/mol at 25°C.  Find the equilibrium constant (Kp) for this reaction at 75 °C.
