For the chemical equilibrium C a C O 3 ( s ) ⇌ C a O ( s ) + C O 2 ( g ) , Δ H ° can be determined from which one of the following graphs?

Correct answer

Step-by-step solution

For the reaction C a C O 3 ⇌ C a O s + C O 2 g ; K = P C O 2 ΔG o = − RTlnK ... (i) ΔG o = ΔH o − TΔS o ... (i) Now, by equating above two equations. lnK = − ΔH o RT + ΔS o R ⇒ log K = − ΔH o 2 .303 R × 1 T + ΔS o 2 .303 R
