1. Describe how temperature and concentration affect the equillibrium of a chemical system.
Increasing the temperature of an exothermic reaction (where the heat term is on the right) will drive the equilibrium to the left whereas increasing the temperature of an endothermic reaction (where the heat term is on the left) will drive the equilibrium to the right.
Similarly, if we increase the concentration of any chemical species in a reaction, the equilibrium will shift away from that compound. In the following,
A + B <-------> C + D
if we increase the ...
