Why does a small particle size generally cause a reaction to proceed faster?
a. the only reason is that there are more collisions per second.
b. the collisions occur with greater energy.
c. there are more collisions per second and the collisions are of greater energy.
d. none of these

Answer:   [a]:   "slate" .

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
