In order for reactants to form products, they have to overcome what barrier?
The speed at which reactant molecules form product molecules is known as the _______.
Adding energy to chemical reactants will ______.
Which of the following variables does NOT affect reaction rate ______.
A catalyst speeds a chemical reaction by increasing its activation energy?
In your new job as chemical engineer, your supervisor asks you to maximize the reaction rate in a chemical plant. The reaction occurs in the liquid phase and already uses a catalyst. Which is the best option to accomplish your assignment?
Using the same chemical reaction from the previous question, consider two test tubes labeled A and B that contain hydrochloric acid solutions with different concentrations. The solution in test tube A is twice as concentrated as the solution in test tube B. Assuming you drop equal amounts of solid magnesium into both test tubes, in which test tube will the reaction occur faster?
Now consider that Test tube A and B from the previous question have the same concentration of hydrochloric acid. If you stirred test tube B while adding the magnesium, but did not stir test tube A, in which tube would the reaction occur faster?
You are designing a chemical process that will separate hydrogen from ammonia according to the reaction below. To keep the reaction rate as fast as possible, you decide your design needs to include _______.
