What is the activation energy?

What is the net chemical reaction associated with the Chapman cycle?

Sketch energy diagrams to represent each of the following. Label the diagrams completely and tell how they are similar to each other and how they are different. a. Exothermic exergonic reaction with activation energy b. Exothermic exergonic reaction without activation energy

Draw an energy diagram graph for an endothermic reaction where no catalyst is present. Then draw an energy diagram graph for the same reaction when a catalyst is present. Indicate the similarities and differences between the two diagrams.

. Account for the increase in reaction rate brought about by a catalyst.

Why are so many different enzymes needed?

Apply collision theory to explain why increasing the concentration of a reactant usually increases the reaction rate.

The equilibrium constant expression for a given reaction depends on how the equilibrium equation is written. Explain the meaning of that statement. You may, if you wish, use the equilibrium equation N2(g)+3H2(g)2NH3(g) to illustrate your explanation.

use the kineticmolecular theory to explain why an increase in temperature increases reaction rate.

List two ways that enzyme catalysis of a reaction is superior to normal conditions.
