Detailed explanation-1: -Increasing the concentration of the reactants will increase the frequency of collisions between the two reactants. When collisions occur, they do not always result in a reaction (atoms misaligned or insufficient energy, etc.). Higher concentrations mean more collisions and more opportunities for reaction.
Detailed explanation-2: -Increasing the temperature increases the average speed of the reactant molecules. As more molecules move faster, the number of molecules moving fast enough to react increases, which results in faster formation of products.
Detailed explanation-3: -Concentration. If the concentration of reactants is increased, there are more reactant particles moving together. There will be more collisions and so the reaction rate is increased. The higher the concentration of reactants, the faster the rate of a reaction will be.
Detailed explanation-4: -If the concentration of a reactant is increased, more product(s) will be formed faster as long as there is enough of the other reactant. If the concentration of reactants is decreased, less product will be formed and/or at a slower rate.
Detailed explanation-5: -Expert-Verified Answer Increasing the temperature increases the average speed of the reactant molecules.
