Which fator can decrease the rate for chemical reactions. A. Low activation energy, B. hight pressure, C. low temperature. D. high concentration of reactants

Low temperature will slow the chemical reaction.

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei and can often be described by a chemical equation.

C - Low temperature

When you lower the temperature, the molecules are slower and collide less. That temperature drop lowers the rate of the reaction.
