Which of the following statements regarding reaction rates and kinetic molecular

Question

Which of the following statements regarding reaction rates and kinetic molecular theory is NOT true? a. Higher concentrations of reactants typically lead to greater reaction rates because a larger 12. b. Collisions between product molecules that reform reactant molecules do not affect the c- The actual dependence of reaction rate on concentration must be determined d. At 0, the maximum rate should be observed because only reactant molecules are e. As the reaction proceeds, fewer reactant molecules are present and the reaction rate number of effective molecular collisions occur. overall rate of reaction. experimentally because it depends on the reaction mechanism. present ypically decreases.

Explanation / Answer

Option D is not true

Because initial rate of reaction increase because of the higher concentration of reactants concentration and larger collision occurs then after time t = t the reaction rate reaches its maximum and then decrease.

A - true

Initial concentration leads to larger collision and the reaction rate is greater.

B - true

Collision between product and collision between reactants both affects the reaction rate

C - true

Actual dependence is an experimental procedure

E - true

Reaction proceeds, concentration of reactants decreases, so the reaction rate decrease.
