Question

1. The equilibrium constant K for the reaction
2HI(g) = H2(g) +12 (g) at room temperature 300 K
is 2.85 and at 698 K 1.84 x 10-2. Hence the reason that
HI exists as a stable compound at room temperature is
because:
(a) it decomposes so slowly that equilibrium is not
readily achieved
(b) the HI bond has a large covalent contribution
(c) the heat of reaction at room temperature is -5.31 kcal
(d) it is uncatalytic reaction​

Answer 1

Answer:

d it is uncatalytic reaction
