Breaking the bonds of the reactants requires energy; bond formation releases energy. Which of the statements regarding energy changes during a reaction are true? The activation energy (Ea) is the energy difference between the energy of the products and the energy of the reactants. If the energy of the products is higher than the energy of the reactants, the reaction is exothermic. O Decreasing the temperature decreases the kinetic energy of the reactants, and the reaction goes more slowly. Increasing the amount of reactants increases the number of collisions, and the reaction goes faster. Reactants must collide, with proper orientation, with energy greater than or equal to the activation energy for a reaction to occur. The energy of a collision between atoms or molecules must be greater than or equal to the activation energy (E.) for bonds to be broken.

In an exothermic chemical reaction O heat is released as the reaction proceeds. the mass of the products is greater than the mass of the reactants. the mass of the products is less than the mass of the reactants. O heat is absorbed as the reaction proceeds.
Chemical reactions occur when molecules or atoms collide in a way that the bonds between atoms break and new bonds form. Breaking the bonds of the reactants requires energy, whereas bond formation releases energy. Select the true statements regarding energy changes during a reaction. When the activation energy is high, the reaction rate is fast. If the heat of reaction, AH, is positive, the energy of the products is lower than the energy of the reactants and the reaction is exothermic. Decreasing the temperature decreases the kinetic energy of the reactants, and the reaction goes more slowly. 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. Increasing the concentration of reactants increases the number of collisions, and the reaction goes faster. Reactants must collide with proper orientation and with energy greater than or equal to the activation energy for a reaction to occur. The activation…

In order to break water into hydrogen and oxygen, water is heated to more than 500°C. Which kind of reaction is this and why? It is exothermic because heat needs to be released by the reactants to form the products. It is endothermic because heat needs to be released by the reactants to form the products It is exothermic because heat needs to be absorbed by the reactants to form the products. It is endothermic because heat needs to be absorbed by the reactants to form the products.
