to find the new rate when the concentration of reactants changes
Explanation:
The rate of a chemical reaction is the rate of change of concentration of reactants or products with time. As a reaction progresses the concentration of reactant decreases and the concentration of product increases. The rate law is the product of the rate constant and the molar concentration of the reactant(s) involved in the chemical reaction. Due to direct proportionality between rate law and concentration of reactants, the rate law is directly affected by the change in the concentration of the reactants.
combustion is a high-temperature exothermic redox chemical reaction between a fuel and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.
