Approximately 75% of the hydrogen used in industry is obtained by the following two-stage method. In the first step, the mixture of steam and methane is passed over a nickel catalyst at 30 atm and heated at 8000C to yield hydrogen and carbon monoxide. In the second stage, air at 10000C is heated to convert the remaining methane into hydrogen. In the first and second stages, at what temperature and pressure the reaction favors product formation. In the first stage, the equilibrium constant at 8000C is Kc, 18. Calculate the Kp value for the reaction. If the initial partial pressures of both methane and steam are 15 atm, what are the pressures of all the gases in equilibrium?

Approximately 75% of the hydrogen used in industry is obtained by the following two-stage method. In the first step, the mixture of steam and methane is passed over a nickel catalyst at 30 atm and heated at 8000C to yield hydrogen and carbon monoxide.
In the second stage, air at 10000C is heated to convert the remaining methane into hydrogen.
In the first and second stages, at what temperature and pressure the reaction favors product formation.
In the first stage, the equilibrium constant at 8000C is Kc, 18.
Calculate the Kp value for the reaction.
If the initial partial pressures of both methane and steam are 15 atm, what are the pressures of all the gases in equilibrium?
