Answer:

D. Catalysts speed up the rate of reactions by lowering the amount of energy required for the reaction to proceed.

Explanation:

A catalyst is a substance that:

  • speeds up the rate of a reaction .
  • does not alter the products of the reaction .
  • is unchanged chemically and in mass at the end of the reaction.

<em>A catalyst provides an alternative reaction pathway that has a lower activation energy than the uncatalyzed reaction. </em>

<em></em>

The figure shows how the energy of the reactants and products change during a reaction.

How can professionals increase their levels of stress as a result of personal work habits?
zmey [24]

Answer:

A

Explanation:

Developing work ethics won't lower your stress although it may make your conscience a little happier. Not B

Not C. Procrastinating just makes things harder. The mountain of things to do is not diminishing at all and your stress knows it.

Not D. Although D is the second best answer, setting goals is not really an action. It is a plan for how to work. But it is not work. Still having a goal is useful.

The answer is A. Just keep hitting what you have to do at a steady pace.
