Solutions

Expert Solution

A)
Forward reaction is exothermic in nature
we are increasing temperature or adding heat here
so, according to Le Chatellier's principle,
equilibrium will move in direction which absorbs heat
hence, backward reaction will be favoured
Answer: Shifts left

B)
Forward reaction is exothermic in nature
we are decreasing temperature or removing heat here
so, according to Le Chatellier's principle,
equilibrium will move in direction which release heat
hence, forward reaction will be favoured
Answer: shift right

C)
k decreases with increasing temperature and increases by decreasing temperature
Answer:K decreases when the temperature increases
