Question 1

Nitric acid is formed by the gas-phase hydrolysis of N2O5.  For the reaction N2O5 + H2O → 2HNO3, Ea(forward) = 15 kJ/mol and Ea(reverse) = 51 kJ/mol.  Calculate ΔHrxn.


Question 2

The rate constant for the first-order decomposition of C4H8 at 500°C is 9.2 × 10–3 s–1. How long will it take for 10.0% of a 0.100 M sample of C4H8 to decompose at 500°C?
