For the reaction , `X(s) harr Y(s) + Z(g)`, the plot of ln`(pz)/p^(theta)` versus `10^4/T` is given below (in solid line), where `p_z` is the pressure (in bar) of the gas at temperature T and `p^(theta)`= 1bar
( Given, `(d(lnK))/(d(1/T))= - (DeltaH^(theta))/R`, where the equilibrium constant , `K= p_z/p^(theta)` and the gas constant, R=8.314`JK^(-1)mol^(-1)`
The value of standard enthalpy,`DeltaH^(theta)`(in `kjmol^(-1)`) for the given reaction is ---------`
