If a reaction is said to be exothermic, which of the following statements is a correct deduction from the information?

An exothermic reaction is a type of reaction that releases heat into the surroundings. Therefore, the correct deduction from this information is that the reaction vessel gets hotter as the reaction proceeds. This is because the heat energy released from the reaction is absorbed by the surrounding medium, which in this case is the reaction vessel. The other statements are not necessarily true deductions from the given information. For example, the sign of the enthalpy change (∆H) for an exothermic reaction is negative, not positive. Also, the rate of the reaction can either increase or decrease with time, depending on the specific reaction and conditions. The activation energy is a property of the reactants and is not necessarily related to whether the reaction is exothermic or endothermic.
