explain temperature . coefficient for exothermic and endothermic reactions
The temperature coefficient is a measure of the change in the rate of a chemical reaction with respect to temperature. It is expressed as the percentage change in reaction rate per degree Celsius (or Kelvin) change in temperature.
An exothermic reaction is a chemical reaction that releases heat to its surroundings. This means that the products of the reaction have a lower energy than the reactants, and the excess energy is released as heat.
An endothermic reaction is a chemical reaction that absorbs heat from its surroundings. This means that the products of the reaction have a higher energy than the reactants, and the required energy is taken from the surrounding environment.
In exothermic reactions, an increase in temperature will cause an increase in the reaction rate. This is because the increased temperature provides more energy for the reactant particles to collide with each other, leading to a higher chance of successful collisions and therefore a faster reaction rate.
In endothermic reactions, an increase in temperature will cause a decrease in the reaction rate. This is because the increased temperature causes the reactant particles to have more kinetic energy and move faster, making it more difficult for them to come together and react. As a result, the reaction rate decreases.
