Question

For a particular reaction, ΔH = -99.84 kJ and ΔS = -16.80 J/K. Calculate ΔG for this reaction at 298 K.

Answer 1

To solve this given problem,  we can use the equation below:
ΔG=ΔH - T*ΔS

We are information and values are given and can be used in solving the ΔG of this particular reaction.
ΔH=-99.84kJ
ΔS=-16.80 J/K
T=298K

ΔG=(-99.84kJ)-(298K*-16.80J/K)
ΔG=-94.83kJ

The answer for ΔG is -94.83kJ.
