Gwhy does bread grow mold more quickly at room temperature than in the refrigerator? why does bread grow mold more quickly at room temperature than in the refrigerator? the formation of mold is an endothermic process and low temperatures favor endothermic processes. because of the absence of the sunlight the potential energy of the reactants is lower in the refrigerator. the formation of mold is an example of photochemical process and it cannot occur in an obscure place such as a refrigerator. more reactants will have the energy necessary to proceed to products at room temperature than at refrigerator temperatures.\
