1.	Represent the potential energy / enthalpy change in the following processes graphically. (a) Throwing a stone from the ground to roof. (b) (1)/(2) H_(2(g)) + (1)/(2) CI_(2(g)) hArr HCI_((g)) Delta_(r) H^( Theta ) - 92.32 "kJ mol"^(-1) In which of the processes potential energy/ enthalpy change is contributing factor to the spontaneity ?
Answer» Solution :Representation of potential energy/ENTHALPY CHANGE in the following process : (a) Throwing as stone from the ground to roof. (B) `(1)/(2) H_(2(g)) + (1)/(2) CI_(2(g)) hArr HCI_((g)) , Delta_(R) H^( Theta ) = -92.32 "kJ mol"^(-1)` Energy is increased in (a) and it is decreased in (b) process. Hence, in process (b), enthalpy change is the contributing factor to the spontaneity.
