Generally the reaction rate is higher at high temperature.
Yes and no. Yes before the reaction, No after the reaction.There is potential chemical energy among constituent substances in an exothermic reaction - such as in Hydrogen and Oxygen. When the chemicals combine, the reaction liberates thermal energy that was stored as potential chemical energy before the reaction.During the chemical reaction, the potential energy is converted into thermal (and perhaps other forms, such as light) energy.After the chemical reaction, the thermal energy is disspiated, and the potential energy is gone.
Yes, for ex. thermal energy.
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is endothermic.
For example thermal energy.
The thermal energy released when you strike a match comes from chemical energy of the substances that make up the match head. These substances go through a chemical reaction to give different new substances (products) with less energy (considered at the initial temperature), and thermal energy that flows to the surroundings (heat) at a lower temperature.
Endothermic
When a fuel is burned, it is a combustion reaction. This reaction breaks apart chemical bonds and releases the energy stored in them.
chemical energy in batteries to thermal energy.
a catalyst has no effect in chemical reaction. it only increases or decreases the rate of the chemical reaction.
something about thermal energy
Chemical energy is transfered to thermal energy whenever a chemical bond is broken, and the chemical energy stored in the bond is released as/converted into heat. Likewise, you can also convert a fraction of a species' chemical energy to thermal energy via an exothermic reaction involving that species.
