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 ΔGꝋ = ΔHreactionꝋ - TΔSsystemꝋ When ΔGꝋ 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 (ΔSsystemꝋ ) for a given reaction can be calculated using the standard entropies (Sꝋ ) 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...
Enthalpy of Hydration: Ionic Charge & Radius The standard enthalpy change of hydration (ΔHhydꝋ) is affected by the amount that the ions are attracted to the water molecules The factors which af...
Energy Cycle Calculations The energy cycle involving the enthalpy change of solution (ΔHsolꝋ ), lattice energy (ΔHlattꝋ), and enthalpy change of hydration (ΔHhydꝋ) can be used to calculate the diff...
