Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Products will form faster if ____
A
the particle size of the reactants are larger.
B
temperature is decreased.
C
concentration of the reactants are increased.
D
the reaction is not stirred.
Explanation: 

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: -Therefore, an increase in the concentration of a reactant will lead to a decrease in the amounts of all reactants and an increase in the amounts of all products. An increase in the concentration of a product will lead to a decrease in the amounts of all products and an increase in the amounts of all reactants.

Detailed explanation-3: -Reaction rates generally increase when reactant concentrations are increased. This section examines mathematical expressions called rate laws, which describe the relationships between reactant rates and reactant concentrations.

Detailed explanation-4: -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-5: -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.
