The products from the combustion of a stoichiometric mixture of CO and O2 are at a pressure of latm and a certain temperature. The products analysis shows that 35% of each kmol if CO, is dissociated. Determine the equilibrium constant for this temperature, and hence find the percentage dissociation when the products are at the same temperature but compressed to 10 atmospheres.
One Kmol of C8H18 is burned with 100% air containing 25 Kmol of O2. Determine the air-fuel ratio for this combustion process.
