Rajasthan BoardEnglish MediumSTD 11 ScienceChemistry6.1. Equilibrium - 1 (chemical Equilibrium)1 Mark
MCQ
For exothermic reaction, the equilibrium constant
  • A
    Increases with increase of $P$
  • B
    Decreases with increase of $P$
  • C
    Increases with increase of temperature
  • ✓
    Decreases with increase of temperature
✓

Answer

Correct option: D.
Decreases with increase of temperature
d
When the temperature of an exothermic reaction is increased, the reaction will proceed in the backward direction, so as to absorb heat and nullify the effect of increasing temperature.

This will decrease the value of the equilibrium constant $K _{ c }$. In other words, the equilibrium will shift to left.
