9. For the reaction 2N2O5 → 4NO2 + O2, the rate is directly proportional to [N2O5]. At 45°C, 90% of the N2Os reacts in 3600 seconds. Find the value of the rate constant, k.

1. Cyclohexane can be produced from the hydrogenation of benzene according to the reaction C6H6 (g) + 3 H2 (g) ­--> C6H12 (g)                                              Ka = 1.371 at 550 K The reactor temperature is 550K and hydrogen to benzene feed mole ratio is 4.5:1. Estimate the gas composition under equilibrium conditions if the reactor pressure is 30 bar. The following fugacity coefficients are obtained for the species involved: Fugacity coefficient (550K, 30 bar) Cyclohexane 0.907 Benzene 0.919 Hydrogen 1.003

The equilibrium constant for the reaction N₂ + O₂2NO is 1.69 × 10-³ at 2300 K. A mixture consisting of 2 mol of nitrogen and 1.0 mol of oxygen is heated to 2300 K at 1 bar and allowed to come to equilibrium. Calculate the mole fraction of NO at equilibrium.
