WebFactors which affect the rate of a chemical reaction. During a reaction, the reactants are used up and changed into the products; The rate of a chemical reaction can be calculated using the following equation: As a reaction proceeds, the concentration of the reactants is decreasing and the concentration of the products is increasing WebPhysical state of reactants. Powders react faster than blocks - greater surface area and since the reaction occurs at the surface we get a faster rate. The presence (and concentration/physical form) of a catalyst (or inhibitor). A catalyst speeds up a reaction, an inhibitor slows it down.
WebFeb 22, 2024 · Increasing the temperature of a reaction increases the number of effective collisions between reacting particles, so the reaction rate increases. Summary Factors that affect (and generally increase) reaction rate are: Concentration of reactants Pressure (in the case of a gas) Surface area Temperature
