The drain cleaner, Drainex contains small birts of aluminium which react with caustic soda to produce dihydrogen. What volume of dihydrogen at `20^@C` and one bar will be released when 0.15g of aluminium reacts?

Dihydrogen gas used in Haber's process is produced by reacting methane form natural gas with high temperature steam..The first stange reaction involves the formation of CO and H_2 .In second stage , CO formed in first stage,CO formed in first stage is reacted with more steam ion water gas shift reaction, CO(g)+ h_2o(g) hArr CO_2(g) +H_2(g) If a reaction vessel at 400^@C is charged with a n equimolar mixture of CO and steam such that P_(co) =P_(H_2O) = 4.0 bar what will be the partial pressure of H_2 at equilibrium? k_p =0.1
