Chemical equations without the spectators are called net ionic equations. Principle Le Ch telier s principle is the quintessential tool for qualitative analysis of chemical reactions. It states that reactions in equilibrium are dynamic and respond to stress or perturbations in a logical way. For instance, add more reactants to a reaction at equilibrium, and the reaction shifts to make more products and return to a balanced equilibrium. Remove some reactants and the reaction shifts into reverse to replace them.
Heat can be a reactant or product too.
This makes perfect sense if you remember that chemical equilibrium is dynamic. Page 95 We will put this principle to work in this investigation by coupling it with our understanding of the meaning of the size of K. Consider the following process. From Table 1, we can see that this is the same situation as the lead nitrate and sodium sulfate discussed before. You will work out the details in the prelab. Le Ch telier would say yes here s why.
