Acrylic acid is produced from propylene by the following gas phase reaction: a significant side reaction is the formation of acetic acid: the reactions are carried out at 310°c and 4 bar pressure using a catalyst and air as an oxidant. steam is added in the ratio 8: 1 steam to propylene to stabilize the heat of reaction. if 50% excess air is used (sufficient air so that 50% more oxygen is present than is needed for all the propylene to react by the first reaction), calculate the equilibrium composition of the reactor effluent.
