| Questão | Responda |
| What is k in a rate equation? | Rate Constant |
| What is the overall order of reaction? | The sum of the powers of each species in the rate equation |
| Units for rate of reaction? | moldm^-3s^-1 |
| Units for concentration? | moldm^-3 |
| Effect on rate when there is a change in concentration if reaction is zero order? | Change in concentration doesn't affect rate of reaction |
| Effect on rate when there is a change in concentration if reaction is first order? | If concentration doubles, rate of reaction doubles; If concentration triples, rate of reaction triples etc.... |
| Arithmetic method to work out order of reaction? | (change in concentration)^order of reaction = change in rate |
| What is the rate determining step? | The slowest step in a chemical reaction: determines how fast a reaction is |
| Which condition(s) affect the rate constant? | ONLY TEMPERATURE AND CATALYST : Pressure and Concentration DO NOT affect rate constant because the concentration of species changes (which is included in rate equation) |
