Question

6.
The equilibrium constant of a homogeneous reaction de-
termined at different temperatures 30°C, 50°C, 70°C and
100°C are 25, 2.5, 0.25 and 0.025 respectively. The data
indicate that the reaction is:​

Answer 1

Equi. constant = conc. of product ÷ conc. of reactant

here, equil. constant decrease continuously by increase in tempereture..

so, the reaction is exothermic..

because according to le chatellier rule rate of exothermic reaction decrease by increase in temperature...
