Equilibrium - Result Question 30

####32. The equilibrium constant for the reaction A2→2A at 500K and 700K are 1×10−10 and 1×10−5 respectively. The given reaction is

[1996]

(a) exothermic

(b) slow

(c) endothermic

(d) fast

Show Answer

Solution:

  1. (b) A2→2A Equilibrium constant is given by Kc=[A]2[A2]

Since the value given is very small, hence conc. of products is less. It means the reaction is slow.
