4. For a reaction at 1 atm Br2(l)→ Br2(g) Where ∆H° = 31.0 kJ/mol and ∆S° = 93.0 J K-1mol-1 What is the normal boiling point of liquid Br2. (10 %)

10. For the reaction between nitric oxide and hydrogen, 2NO(g) + H2(g) →N2O(g) + H2O(g) may proceed via the following mechanism: 1. 2NO \(\xrightarrow{k_1}\) \(\xleftarrow{k_{-1}}\) N2O2 2. N2O2 + H2 \(\xrightarrow{k_2}\) N2O + H2OWrite the rate law for this reaction by using the steady-state approximation if step 2 is the rate-determining step in this mechanism. (10 %)
