A mixture of hydrogen and oxygen is enclosed in a rigid insulated cyclinder. It is ignited by a spark. The temperature and the pressure both increase considerably. Assume that the energy supplied by the spark is negligible, what conclusions may be drawn by application of the first law of thermodynamics?

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

A welding fuel gas contains carbon and hydrogen only. Burning a small sample of it in oxygen gives 3.38 g carbon dioxide, 0.690g of water and no other products. A volume of 10.0L (measured at STP) of this welding gas is found to weigh 11.6 g. Calculate empiracle formula
