Physical change involves a change in state, while chemical change involves a change in properties

Physical change involves a change in properties, while chemical change involves a change in state

Physical change is reversible, while chemical change is irreversible

Physical change does not involve a change in the substance, while chemical change involves a change in the substance

To increase the rate of reaction

To decrease the rate of reaction

To change the products of the reaction

To speed up the reaction without being consumed or altered

Matter can be created or destroyed in a chemical reaction

The total mass of the reactants is less than the total mass of the products

The total mass of the reactants is greater than the total mass of the products

The total mass of the reactants is equal to the total mass of the products

To balance the equation

To identify the type of reaction

To calculate the yield of the reaction

To determine the equilibrium constant

To separate the reactants and products

To indicate the direction of the reaction

To show the equilibrium constant

To calculate the yield of the reaction

Combination reaction is exothermic, while decomposition reaction is endothermic

Combination reaction involves the formation of a new substance, while decomposition reaction involves the breakdown of a substance

Combination reaction is a physical change, while decomposition reaction is a chemical change

Combination reaction occurs at high temperature, while decomposition reaction occurs at low temperature
