H2 A-Level Chemistry deck for H2 A-Level Chemistry students, containing H2 A-Level Chemistry cards with H2 A-Level Chemistry answers.
| Front | How does a catalyst affect the rate constant |
| Back | From the rate equation, \(Rate=k[A]^m[B]^n\). If [A] and [B] are constant, \(Rate\propto k\). When a catalyst is used, rate increases, so k must have increased. |
| Front | How to determine hybridisation? |
| Back | Look at the number of pi bonds. |
| Front | Why do real gases to behave similar to ideal gases at low pressure? |
| Back | At low pressure, the gas molecules are very far apart with a large amount of space between each molecule. This makes the volume of the gas particles negligible compared to the volume of container. In addition, since the molecules are further apart, intermolecular forces are more negligible as well. The collisions become more elastic as well. |
