A)The reaction is exothermic (-
Δ H)as demonstrated by the warm reaction vessel and entropy is increased (+
Δ S). The reaction has a negative
Δ G and is, therefore, spontaneous.
B)The reaction is exothermic (+
Δ H)as demonstrated by the warm reaction vessel and entropy is increased (+
Δ S). The reaction therefore has a negative
Δ G and is, therefore, spontaneous.
C)The reaction is exothermic (+
Δ H)as demonstrated by the warm reaction vessel and entropy is increased (-
Δ S). The reaction has a positive
Δ G and is, therefore, spontaneous.
D)The reaction is endothermic (-
Δ H)as demonstrated by the warm reaction vessel and entropy is increased (-
Δ S). The reaction has a positive
Δ G and is, therefore, spontaneous.
