Select the correct answer.
why does every chemical reaction require a certain amount of activation energy?
o a
energy is released when the reactants begin to react.
o b. energy lost to the environment during the reaction must be replaced.
oc forming the activated complex requires energy.
od. the products have more potential energy than the activated complex.
o e.
the reactants have less potential energy than the products.

The first one

Explanation:

Out of those I'd say the first ones the most right, chemical bonds have to be broken to start a chemical reaction which is exothermic and does release energy.

So yea the top one I reckon.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
