1.	(I) What is the effect of pressure on the equilibrium of the reactionbetween nitrogen and oxygen to give nitric oxide ? (II) In a reversible reaction, some amount of heat energy is liberated in th forward reaction. Name the reaction . What change in temperature favours the forward reaction ?
Answer» Solution :(i) `N_(2) + O_(2) hArr 2NO` As the TOTAL number of moles on reactantsside and products side is same, there is no effect of pressure on the EQUILIBRIUM . (ii) In a reversible REACTION, EVOLUTION of heat indicates that it is an exothermic reaction and `DeltaH=-ve` For example ,`A + B hArr C+B + ` Energy Hence, low temperature favours the formation of products.
