Construct an argument using collision theory and transition state theory to explain the role of activation energy in chemical reactions.

There is a single path for electrons. the current decreases when additional resistors are added. the current will be the same in each resistor. these statements best describe a(n) circuit.

Which is not true regarding reaction rates? (2 points) catalysts are not used up in the reaction. catalysts speed up reactions by lowering the activation energy. reaction rates decrease as the concentration of reactants decrease. during reactions, concentrations of all reactants decrease at the same rate.

Food can lose electrons to air. this loss of electrons can create free radicals that destroy chemical bonds, hence spoiling the food. which term describes this process?
