Study Notes
Chemical Catalysts
- Catalysts speed up chemical reactions by providing an alternate reaction pathway with a lower activation energy.
- They do not get consumed in the reaction and can be used repeatedly.
Solubility
- Generally, "like dissolves like" meaning polar solvents dissolve polar solutes and non-polar solvents dissolve non-polar solutes.
Exothermic Reactions
- Exothermic reactions release heat into their surroundings causing a temperature increase in the system.
Pressure and Equilibrium
- Increasing pressure on a gaseous reaction favors the side with fewer moles of gas to relieve the pressure.
Chemical Bonding
- Covalent bonds involve the sharing of electron pairs between atoms.
