For exothermic reaction (that is heat is considered as a product) then
reactants= product + Energy ,
An decrease in temperature favors the forward reaction (more product formed)
pressure depends on number of mole of the product and reactants
a A + b B + c C + d D (Where a b c and d are numerical value and A B C and D are compounds) :
if more A is added to the equilibrium mixture, equilibrium position will shift to the right (more product formed) so as to decrease concentration of A
