1.	Represent the potential energy // enthalpychange in the followingprocesses graphically : (a) Throwing astone from the ground to roof. (b)(1)/(2)H_(2)(g)+(1)/(2)Cl_(2)(g)hArr HCl(g) Delta_(r)H^(c-) = - 92.32kJ mol^(-1) In which of the following processpotential energy // enthalpy change is contributing factor to the spontaneity ?
Answer» Solution : ENERGY INCREASES in (a) and it decreases in (b). HENCE, in process (b), ENTHALPYCHANGE is the CONTRIBUTING factorto the spontaneity.
