WebSep 16, 2024 · O 2(g) + H 2(g) → H 2O(l) There are times when the rate of a reaction needs to be slowed down. Lowering the temperature could also be used to decrease the number of collisions that would occur and lowering the temperature would also reduce the kinetic energy available for activation energy.

WebThere are several factors that can affect the rate of a reaction. These are: Concentration of the reactants in solution or the pressure of reacting gases Temperature at which the reaction is carried out Surface area of solid reactants The use of a catalyst Changes in these factors directly influence the rate of a reaction WebThe rate of reaction increases when we increase the surface area of a solid reactant. This means they have more particles on the surface so there is more collisions per second. … WebStudy Guides for General Chemistry 2. 1. Liquids.

WebApr 11, 2024 · Temperatures beyond the optimum denature most enzymes. The concentration of the chemical reactants also affects the rate of reaction by altering the number of reacting molecules. A higher concentration increases the number of molecules available for collision. This increases the rate of collision and hence the rate of reaction. Web- reactants react and their concentrations fall, so the forwards reaction slows down - as more products are made their concentration rises so the backwards reaction speeds up - soon they both go at same rate - there's no overall effect (dynamic equilibrium) - it's only reached in a close system - doesn't mean the amount of each is equal
