The reaction Br2(g) → 2Br(g) is spontaneous only at temperatures in excess of 1600°C. We can conclude that: a. ΔH is + and ΔS is + for the reaction.
b. ΔH is – and ΔS is + for the reaction.
c. ΔG is + for all temperatures.
d. ΔH is – and ΔS is – for the reaction.
e. ΔH is + and ΔS is – for the reaction.
