A Level Chemistry

The aims and objectives of the Pearson Edexcel Level 3 Advanced GCE in Chemistry are to enable students to develop: • essential knowledge and understanding of different areas of the subject and how they relate to each other • a deep appreciation of the skills knowledge and understanding of scientific methods

How can a rate equation be deduced from a reaction mechanism?
The order of a reactant and thus the rate equation can be deduced from a reaction mechanism if the rate-determining step is known For example, the reaction of nitrogen oxide (NO) with hydrogen (H 2) to form nitrogen (N 2) and water N2O2 (g) + H2 (g) → H2O (l) + N2O (g) slow (rate-determining step)
What is Edexcel chemistry?
Chemistry A level Edexcel a reaction in which one molecule combines with another to form a larger molecule with no other products. Involves breaking a pi bond The removal of a molecule from a saturated molecule to make an unsaturated molecule. A pi-bond is formed
Why are reaction mechanisms important?
Reaction mechanisms can help us understand fundamentals like order of reaction and rate-determining steps in a chemical process. Not all steps in a reaction mechanism occur at the same speed. The slowest step is known as the “rate-determining step” because it determines the overall rate of the reaction.
What is a one step reaction mechanism?
A one step reaction mechanism is simply the overall stoichiometric equation One of the two elementary steps for this two step mechanism can be taken from the question: The second elementary step must involve the reaction of the nitrogen dioxide formed with sulfur dioxide: Elementary step 2: NO 2 + SO 2 → NO + SO 3 (or 2NO 2 + 2SO 2 → 2NO + 2SO 3)
