GO STUDY EQUILIBRIUM !

since the forward reaction is exothermic , if you increase the temperature ! equilbibrium will want to decrease the temperature ! ( it does the opposite of what u want ) and to decrease the the temperature , it moves in the endothermic direction  ( opposite to the exothermic dircetion )  so equilibrium moves from right to left  and so onow equilibrium is in the REACTANT SIDE AND SO  reactants yield = amount , incrase and producti decrease , because its equilibrium if one increase the other has to decrease
