Answer
Reaction will shift towards left side(reactants).
Reaction will shift towards right side(products).
Value of equilibrium constant decreases on increasing temperature and increases on decreasing temperature.
Work Step by Step
As the given reaction is exothermic so heat is evolved in products.
On increasing temperature according to Le Chatelier's principle the equilibrium will shift towards left side(reactants) to minimize the effect of excess heat.
Again on decreasing the temperature according to Le Chatelier's principle the equilibrium will shift towards right side(products).
On increasing temperature as the reaction shift towards left side amount/concentration of products in equilibrium mixture decreases as a result value of equilibrium constant decreases.Similarly on decreasing temperature value of equilibrium constant increases.
