For 30 points!me understand this question
which of the following conditions results in an activation energy that allows the reaction to occur more easily?
a) decreasing the surface area of the particles
b) reducing the concentrations of reactant molecules
c) decreasing the temperature
d) adding a catalyst

D) Adding a catalyst

Explanation:

Adding a catalyst decreases activation energy and allows the reaction to occur more easily.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

the answer is a and have a great day
