  30. Multiple Reactions A bed of coal (assume pure carbon) in a coal gasifier is fed with steam and air and produce a gas stream containing H2, CO, O2, H2O, CO2, and N2. If the feed to the gasifier consists of 1 mol of steam and 2.38 mol of air, calculate the equilibrium composition of the gas stream at P = 20 bar.
