1. Consider the following reaction occurring in a closed chemical system. Assume that this reaction is at equilibrium and that in general the reaction to the right is favored.

CH3CH2OH + 3O2 2CO2 + 3H2O∆H = - 1,235 kJ/mol

•What type of chemical reaction is this?

•If more CH3CH2OH is added to the system, how will the reactions shift to reach equilibrium again?

•If water is extracted from the system, how will the reactions shift to reach equilibrium again?

•If heat is removed from the system, how will the reactions shift to reach equilibrium again?

•What is the name of the principle

This is an exothermic reaction.

The equilibrium will shift to the right to consume the reactant and counter this change.

The equilibrium will shift to the right to produce more water and counter this change.

The equilibrium will shift to the right to produce more heat and counter this change.

This is known as Le Chatelier's principle and it states that when a change is produced in an equilibrium system, the system will shift in a manner so as to counteract the change.
