Inv 12 Exp 2 - Progress of Chem Reactions - Day 1

True or False. The activated complex will have higher energy than the products only if the reaction is exothermic.

• True

• False

The energy required to drive the reactants to the activated complex of a reaction is called.

• Activation Energy

• Heat of Reaction

• Formation Energy

• Chemical Potential Energy.

Which section of the diagram best describes the activation energy?

• A

• B

• C

• D

• E

The reactants gain energy to get to point "D" in the diagram, which is called _____

• The Activation Complex.

• The Halfway Point

• The Intermediate Product

• The Bump

The reaction shown on the diagram is (endothermic / exothermic?), we know because as shown in label (B/C/E?) the products have (more/less?) energy than the reactants

• exothermic ; C ; more

• endothermic ; E ; more

• endothermic; B; less

• exothermic; E ; less

True or False. Catalyst are involved in an alternate path of reaction that takes less energy and thus facilitate the reaction.

• True

• False

True or False. A catalyst is consumed in very small amounts as part of the reaction but gives great benefits in speed of reaction.

• True

• False
