For the decomposition of MgCO 3 ( s ) ​ at 100 0 ∘ C , Δ G 0 = − 27 KJ / Mole and P CO 2 ​ ​ = 0.0033 atm , then Δ G for the given reaction is _________ ( MgCO 3 ( s ) ​ → MgO ( s ) ​ + CO 2 ( g ) ​ )

TestHub · Accepted Answer

Kp = ( P CO 2 ​ ​ ) = 0.0033 atm , Δ G = [ Δ G 0 + 2.303 RT lo g Kp ] ​ Δ G = ( − 27 × 1 0 3 ) + [ 2.303 × 8.314 × 1273 × lo g 0.0033 ] ​ ​ Δ = ( − 27 − 60.5 ) = − 87.5 KJ / mole , Δ G = − 87.5 KJ / mole
