If ΔH° for this reaction is

K

Step 1

The expression for van’t Hoff equation is expressed in equation (1) in which K_{P1} and K_{P2} are equilibrium constants, T_{1} and T_{2} are two different temperatures, ∆H^{○} is the enthalpy for the reaction and R is the gas constant.

The relation between joule and kilojoule is labelled in equation (2).

Step 2

Convert 182 kJ into joules by using the equation (2).

182 kJ = 182 ×1000J

= 182000 J

Step 3

Use the equation (2) and substitute 0.215 for KP1, 673 K for T1, 764 K for T2 , 8.314 J/K.mol for R and 182000 J/mol for ∆H○ as shown below i...
