Subject: Physical Chemistry · Chapter: Chemical Equilibrium · Topic: Chemical Equilibrium – General · Exam: JAM 2001-2022 · Marks: 2 · Difficulty: Medium
The temperature ( T ) dependence of the equilibrium constant ( K ) of a chemical reaction is correctly described by the following statement:
(a)For an endothermic reaction, the slope of $\ln \mathrm{K}$ vs $1 / \mathrm{T}$ plot is positive.
(b)For an exothermic reaction, K is proportional to T
(c)For an exothermic reaction, K at a higher temperature is lower than K at a lower temperature
(d)If $\Delta \mathrm{H}$ is independent of temperature, the change in K with T is smaller at lower temperatures.
