Plz 10 how can the rate of a reaction be decreased? a. having more surface area b. raising the temperature c. lowering the amount of reactants d. adding a catalyst

Answer;

D. Lowering the amount of reactants

Explanation;The rate of reaction is the measure of the extent at which reactants are being converted to products. The rate of a reaction determines or shows the speed at which a particular chemical reaction is taking place. The rate of reaction is determined by various factors which includes; the temperature, the concentration of the reactants, the size of particles of the reactants in the case of solid reactants, adding a catalyst etc.Increasing the temperature of a reaction increases the rate of reaction as the vibration of particles increases thus increase in the number of collisions. Adding a catalyst also increases the rate of reaction as it reduces the amount of activation energy. Increasing surface are of particles of reactants for solid reactants also increases the rate of reaction as well.

Multiply the 3 dimensions, assuming it is a rectangular cuboid, to get the volume in cm³ divide mass by volume to get density in g/cm³
