Breaking the bonds of the reactants requires energy, whereas bond formation releases energy. Select the true statements regarding energy changes during a reaction. Attempt 1 The energy of a collision between atoms or molecules must be greater than or equal to the activation energy, Ea, for bonds to be broken. When the activation energy is high, the reaction rate is fast. The activation energy, Ea, of the forward reaction is the difference between the energy of the products and the energy of the transition state. Decreasing the temperature decreases the kinetic energy of the reactants, and the reaction goes more slowly. Reactants must collide with proper orientation and with energy greater than or equal to the activation energy for a reaction to occur. Increasing the concentration of reactants increases the number of collisions,…arrow_forwardDetermine rxnH 25 C for the following reaction: NO g O2 g NO2 g This reaction is a major participant in the formation of smog.arrow_forward
