Edexcel A Level Chemistry:復習筆記6.1.1 Reduction & Oxidation
Reduction & Oxidation To recap, there are three definitions of?oxidation?and?reduction? used in different branches of chemistry Oxidation?and?reduction?can be used to describe any of the...
Edexcel A Level Chemistry:復習筆記5.5.9 Arrhenius & Activation Energy
Arrhenius & Activation Energy The rate equation shows how each of the reactants in a reaction effects the rate of the reaction and it includes the rate constant,?k However,?k?only remain...
Edexcel A Level Chemistry:復習筆記5.5.8 Rates & Reaction Mechanisms
Deducing Reaction Mechanisms Chemical kinetics can only?suggest?a reaction mechanism, they cannot prove it However, they can be used to disprove a proposed mechanism Elementary steps ...
Edexcel A Level Chemistry:復習筆記5.5.7 Rate-Determining Steps
Deducing Rate-Determining Steps Rate-determining step & intermediates A chemical reaction can only go as fast as the slowest part of the reaction So, the?rate-determining step?is the slo...
Edexcel A Level Chemistry:復習筆記5.5.6 Reaction Order Graphs
Reaction Order Graphs Reaction Order Using Concentration-Time Graphs In a?zero-order?reaction, the concentration of the reactant is inversely proportional to time This means that the reactan...
Edexcel A Level Chemistry:復習筆記5.5.5 Continuous Monitoring Method
Continuous Monitoring Method Continuous?monitoring?involves collecting experimental data throughout the course of a reaction to plot a concentration-time graph Two of the most common ways to...
Edexcel A Level Chemistry:復習筆記5.5.4 Initial Rates Method
Initial Rates Methods The?initial rates method?determines the rate at the very start of the reaction when?t?= 0 The initial rate can be found by: Drawing a?concentration-time graph Adding a?...
Edexcel A Level Chemistry:復習筆記5.5.3 Rates - Experimental Techniques
Rates - Experimental Techniques To measure the?rate of a reaction, we need to be able to measure either how quickly the reactants are used up or how quickly the products are formed The metho...
Edexcel A Level Chemistry:復習筆記5.5.2 Rate Equations
Orders of Reaction The?order?of a reactant shows how the concentration of a chemical, typically a reactant, affects the rate of reaction It is the power to which the concentration of that re...
