Problem Details

Calculate the standard entropy, Δ S°rxn, of the following reaction at 25.0 °C using the data in this table. The standard enthalpy of the reaction, ΔH°rxn, is -44.2 kJ•mol-1

C2H4 (g) + H2O (l) →C2H5OH(l)

ΔS °rxn = ________ J•K-1 •mol-1

Then, calculate the standard Gibbs free energy of the reaction, Δ G °rxn.

ΔG°rxn = _______kJ•mol-1

Finally, determine which direction the reaction is spontaneous as written at 25.0 °C and standard pressure

a) forward

b) reverse

c) both

d) neither
