Arrhenius equation Study guides, Revision notes & Summaries

This is a summary of every learning objective (a-j) for Topic 6, CI on the OCR Chemistry B (Salters-Nuffield) specification. I have arranged my notes answering each objective, and have given definitions, equations, techniques, and other notes based on the textbook and my lessons. These notes include rates of reaction, the Arrhenius equation, Kc, nitrogen oxides, nitrate and ammonium ion tests, and more. Selling these as cheaper as this is a short topic! I used these notes for my Chemistry ex...

The experimental rate law for the decomposition of nitrous oxide (N2O) to N2 and O2 is Rate = k[N2O]2 . Two mechanisms are proposed: I. N2O  N2 + O N2O + O  N2 + O2 II. 2N2O N4O2 N4O2  2N2 + O2 Which of the following could be a correct mechanism? A) Mechanism I, with the first step as the rate-determining step. B) Mechanism I, with the second step as the rate-determining step as long as the first step is a fast equilibrium step. C) Mechanism II, with the second step as the ra...

REACTOR (CSTR) EXPERIMENT 2024 MCKETTA DEPARTMENT OF CHEMICAL ENGINEERING THE UNIVERSITY OF TEXAS AT AUSTIN ACTUAL SPRING 2024 INTRODUCTION This experiment involves a chemical reaction in a 2L continuous-flow stirred tank reactor (CSTR). The conversion in the reactor is related to the kinetic information and reactor operating conditions. The reaction to be studied, the saponification of ethyl acetate by sodium hydroxide, is especially convenient for this study because the conductivity ...

Express this number in standard scientific notation. 3. Question: The state of matter for an object that has both definite volume and definite shape is 4. Question: How many of the following numbers contain 3 significant figures? 5. Question: In the spring of 2008, gasoline cost £1.029 per Liter in London. On the ...

Polarimetry, Spectroscopy, Pressure Measurement Three ways to measure a change in concentration Gas chromatography, mass spectrometry, titration Methods used to measure slow reactions with aliquots Zero Order Reaction rate of the reaction is independent of the concentration of the reactant Rate = k[A]⁰ = k First Order Reaction rate of the reaction is directly proportional to the concentration of the reactant Rate = k[A]¹ Unimolecular: A → products Second Order Reaction rate of the react...

These are detailed Revision Notes for Topic 1.9 of AQA A-Level Chemistry (Rate Equations). They were written by me using a combination of the textbook and class notes. I will also be uploading the other topics and creating bundles. Topics Included: - The rate of chemical equations - The rate expression and order of reaction - Determining the rate equation - The Arrhenius equation - The rate determining step
