What must be true for any endothermic reaction? The chemical bonds of the products have more energy than the chemical bonds of the reactants. There are more products than there are reactants. There must be a phase change from solid to liquid or from liquid to gas. The reaction must take place in a sealed container held at constant volume.
Weegy: Endothermic describes a process or reaction in which the system absorbs energy from the surroundings in the form of heat. Exothermic is the release of energy in heat form. User: A student notices that a reaction takes place faster when the temperature is higher. Which best explains why this happens? At higher temperatures, the molecules collide more frequently. The heat of the solution breaks apart chemical bonds. As the particles move more quickly, they can more easily avoid each other. Catalysts cannot be effective at high temperatures. Weegy: A User: A chemist finds that when platinum is added to a reaction, the reaction speeds up. He thinks the platinum may be acting as a catalyst. What measurement should the chemist make to determine whether it is a catalyst? Measure the mass of the platinum before and after the reaction. Measure the temperature of the solution before and after the reaction. Measure the change in volume of the solution. Measure the amount of gas released by the reaction. Weegy: Measure the mass of the platinum before and after the reaction. Catalysts themselves do not undergo any changes so the mass should be the same. (More)
