| What do rate equations tell you? | How the rate is affected by the concentrations of reactants |
| What is the rate equation for the general equation: A + B --> C + D | Rate = k[A]ᵐ [B]ⁿ m and n are orders of reaction k is the rate constant |
| TRUE OR FALSE: The units of k vary | TRUE |
| TRUE OR FALSE: The rate constant of a first order reaction is equal tot he gradient of the rate-concentration graph of that reactant | TRUE |
| What is half-life (of a reaction)? | The time it takes for half of the reactant to be used up. It can be calculated from a concentration-time graph |
| TRUE OR FALSE: The half-life of a zero order reaction is independent of the concentration. | FALSE The half-life of a FIRST order reaction is independent of the concentration |
| Given the half-life of a first order reaction, what is the equation used to work out k? |
