Represent the potential energy/enthalpy change in the following proces

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) Cl_(2) (g) hArr HCl (g) Delta_(r) H^(Θ) = - 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 energylenthalpy change in the following PROCESSES (a) Throwing a stone from the ground to roof. (b) `(1)/(2) H_(2) (g) + (1)/(2) Cl_(2) (g) hArr HCl (g) , Delta_(f) H^(Θ) = - 92.32 kJ MOL^(-1)` Energy increases in (a) and it decreases in (b) PROCESS. Hence, in process (b), enthalpy change is the contributing FACTOR to the spontaneity
