Question

5) determine which reactions below are endothermic (make only 1 choice, even if there is more than 1 possible choice) *
a) C (s) + 2S (s) to CS2 (l) ΔH = + 19 kcal
b) Graphite + O2 (g) -> CO2 (g) + 94.1 kcal
c) H2 (g) + I2 (g) + 12.4 kcal → 2HI (g)
d) 2NO (g) - 43.2 kcal → N2 (g) + O2 (g)

Answer 1

Answer:

a) C (s) + 2S (s) to CS2 (l) ΔH = + 19 kcal
