Faraday's Law The?amount?of substance that is formed at an electrode during?electrolysis?is proportional to: The amount of?time?where a constant current to passes The?amount?of?electricity, in coul...
Products of Electrolysis Electrolysis?is the breaking down of a compound into its elements using an?electric current For example, the electrolysis of zinc chloride (ZnCl2) into its elements zinc an...
Feasibility & Temperature Changes The?feasibility?of a reaction can be affected by the?temperature The Gibbs equation will be used to explain what will affect the feasibility of a reaction for ...
The Gibbs Equation: Reaction Feasibility The Gibbs equation can be used to calculate whether a reaction is?feasible?or not ΔG??= ΔHreaction??- TΔSsystem? When ΔG??is?negative, the reaction is?feasi...
The Gibbs Equation Gibbs free energy The feasibility of a reaction does not only depend on the entropy change of the reaction, but can also be affected by the enthalpy change Therefore, using the e...
Calculating Entropy Changes The standard entropy change (ΔSsystem??) for a given reaction can be calculated using the standard entropies (S??) of the reactants and products The equation to calculat...
Defining Entropy The?entropy (S)?of a given system is the number of possible arrangements of the particles and their energy in a given system In other words, it is a measure of how?disordered?a sys...
