<h3>What are equilibrium reactions?</h3>
An equilibrium reaction is a chemical reaction process in which the reactants remain in a steady and stable condition both previously(reactant) and after the reaction is completed(product).
A reaction is considered to be at thermodynamic equilibrium when a reaction meets all three categories of equilibrium;
- Equilibrium of temperature
- Equilibrium in the chemical reaction.
- Equilibrium with the surrounding factors like pressure.

a)0 0 0 8 8 10 12 13 15 15 17 20 22 56
median= (12+13)/2 =12.5
mean=14
b) the median due to 56 being a clear outliar that skews the average right (basically increase the average to not be representative of data set)
