GENERAL KNOWLEDGE

Detailed explanation-1: -Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period. Physical state of the reactants and surface area.

Detailed explanation-2: -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-3: -Increasing the concentration of a reactant increases the frequency of collisions between reactants and will, therefore, increase the reaction rate.

Detailed explanation-4: -Concentration is the number of particles of a substance in a given volume. When the concentration of reactants is higher, the reaction rate is faster. At higher concentrations, particles of reactants are crowded closer together, so they are more likely to collide and react.

Detailed explanation-5: -A high concentration has more reactant particles per unit volume available to collide. The more reactant particles there are, the greater the chance of a collision. Therefore there is a high frequency of collisions which increases the frequency of effective collisions resulting in a faster reaction rate.
