"For a given chemical reaction A $\to$ B at 300 K the free energy change is $-$49.4 kJ mol$-$1 and the enthalpy of reaction is 51.4 kJ mol$-$1. The entropy change of the reaction is _____________ JK$-$1 mol$-$1."

Question

Accepted Answer

"$\Delta$G = $-$49.4 kJ/mol

$\Delta$H = 51.4 kJ/mol

$\Delta$G = $\Delta$H $-$ T$\Delta$S

$-$49400 = 51400 $-$ 300$\Delta$S

$\Delta S = {{ + 100800} \over {300}} = 336$ JK^$-$1 mol^$-$1"

For a given chemical reaction A $\to$ B at 300 K the free energy change is $-$49.4 kJ mol^$-$1 and the enthalpy of reaction is 51.4 kJ mol^$-$1. The entropy change of the reaction is _____________ JK^$-$1 mol^$-$1.
