Question

For equilibrium: CO2 (g) + H2 (g) = CO (g) + H2O (g)
K = O.O8 at 4OO ° C and K = 0.41 at 600 ° C. Is the reaction exothermic or endothermic? Explain

Answer 1

Answer:

A2(g)⇌2A(g)

At 400 K, K=1×10

−8

At 600 K, K=1×10

−2

(which is more)

Hence, more reaction occurs at 600 K. Hence the reaction is endothermic.
