Term | Definition |
---|---|
Exothermic | Gives out energy to surroundings usually in heat shown by rise in temp of surroundings |
Endothermic | Takes in energy from surroundings, in heat form, shown by fall in temp in surroundings |
Products lower than reactants | Is Exothermic |
Products higher than reactants | Is Endothermic |
Activation Energy | Minimum energy needed to break bonds (And start it) |
pH scale goes from | 0 - 14 |
Reaction between Acids & Alkali's is | Neutralisation |
Titration Curves | Show pH changes in volume |
Energy Must be supplied to.... | Break Bonds |
Bond Forming | Exothermic |
Bond Breaking | Endothermic |
