Question 1

Estimate ΔrG° for the following reaction at 449.0 K.

CH2O(g) + 2H2(g) → CH4(g) + H2O(g)ΔrH°= -94.9 kJ mol-1; ΔrS°= -224.2 J K-1 mol-1

◦ -4.2 kJ mol-1
◦ +2.4 kJ mol-1
◦ +5.8 kJ mol-1
◦ -101 kJ mol-1
◦ +12.9 kJ mol-1

Question 2

Estimate ΔrG° for the following reaction at 387 K.

HCN(g) + 2H2(g) → CH3NH2(g)ΔrH°= -158.0 kJ mol-1; ΔrS°= -219.9 J K-1 mol-1

◦ -72.9 kJ mol-1
◦ -92.5 kJ mol-1
◦ +243 kJ mol-1
◦ +84.9 kJ mol-1
◦ -188 kJ mol-1
