What types of reactions are always exothermic? A first-order reaction has rate constants 4.6 \times 10^{-2} \ s^{-1} and 8.2\times 10^{-2} \ s^{-1} of and at 0^o C and 20^oC, respectively. What is the value of the activation energy?
What type of reaction is an exothermic reaction? Exothermic reactions arereactions or processes that release energy, usually in the form of heat or light. In an exothermic reaction, energy is released because the total energy of the products is less than the total energy of the reactants. ...
What type of reaction is used in calorimetry? What are the reactants in a neutralization reaction? Is burning a candle a chemical reaction? Is an explosion a chemical reaction? What types of reactions are always exothermic? How does a chemical reaction produce heat?

Thermite process : When highly reactive metals such as Sodium, Calcium, Aluminium etc., are usedas reducing agents they displace metals of lower reactivity from thecom-pound. These are exothermic reactions. The amount of heat evolved is so large that the metals produced in molten state. ...

Nearly all reactions go faster as the temperature increases — exothermic reactions included. The reaction between oxygen in the air and the chemicals in the tip of a match, for example, is so slow at room temperature that nothing seems to happen. When you heat up the tip of the match by...

net reduction in temperature, the reaction is endothermic. It's possible for this to happen because a chemical reaction always proceeds in a way that increases entropy. By contrast, exothermic reactions are those which release heat. Oxidation reactions are usually exothermic such as a burning log....
Which reactions in glycolysis are highly exothermic and why? Is the hydrolysis of ATP endergonic or exergonic? Why? How? Which of the following options is correct? An endergonic reaction a. has + Delta G. b. has + Delta G. c. is anabolic. d. is catabolic. e. Both a and c. f....
