Question

When compared to delta G° for the formation of Al2O3,
deltaG° for the formation of Cr2O3 is a) higher b) lower c)
same d) unpredicted

Raveena Sharma · Accepted Answer

1 Correct option is (A) higher

2 This is because numerically the Gibbs free
energy of formation of Aluminium oxide is higher as it is (-) sign
denotes that more energy is released during the process
