The rate of disappearance equation is used to calculate how quickly a substance is used up or changed in a chemical reaction. It helps determine the speed at which the reaction is happening.
The rate of disappearance formula is used to calculate the speed at which a substance is consumed or transformed in a chemical reaction. It is typically expressed as the change in concentration of the reactant over time.
The average rate of disappearance for a substance in a chemical reaction is the speed at which the substance is used up over time. It is calculated by dividing the change in concentration of the substance by the change in time.
Chemical Change
A substance whose potential chemical energy is transformed into thermal energy is called a fuel. When the fuel undergoes combustion or a chemical reaction, its stored energy is released in the form of heat.
To determine the initial concentration of a substance in a chemical reaction, you can use the formula: initial concentration (final concentration) / (reaction coefficient). This involves knowing the final concentration of the substance and the reaction coefficient from the balanced chemical equation.

Generally chemical energy can be defined as the aptitude of a substance to be transformed in another substance by a chemical reaction.
The original substances are transformed during a chemical reaction a new substance (compound) is obtained.
Chemical Change
You can determine if a substance has undergone a chemical change by observing specific indicators, such as the production of gas (bubbles), a change in color, the formation of a precipitate, or a change in temperature (exothermic or endothermic reactions). Additionally, if the original substance cannot be easily recovered or transformed back into its initial state, it is likely that a chemical change has occurred.
