Answer:
Explanation: a) Reaction is exothermic because heat is released
If temperature is lowered, amount of products is increased,
equilibrium transfers to right
b) If pressure decreases, equilibrium transfers to direction in which amount of gas moles is greater, also in left (reactants)
c) If Oxygen is removed, reaction which produces more oxygen is favoured, also balance changes to reactansts (left)
d) Adding product causes equilibrium transfer to left (reactansts)
