Effect of Ionic Radius on Thermal Stability of Group 2 Nitrates & Carbonates The Group 2 nitrates and carbonates become more thermally stable going down the group The charge density of the cati...
Homogeneous & Heterogeneous Catalysis Catalysts increase the rate of reaction by providing an alternative pathway which has a lower activation energy Catalysts can be either homogeneous or hete...
Effect of Temperature on the Rate Constant At higher temperatures, a greater proportion of molecules have energy greater than than the activation energy Since the rate constant and rate of reaction...
Kinetics of Multi-Step Reactions The reaction mechanism of a reaction describes how many steps are involved in the making and breaking of bonds during a chemical reaction It is the slowest step in ...
Calculating the Rate Constant The rate constant (k) of a reaction can be calculated using: The initial rates and the rate equation The half-life Calculating the rate constant from the initial rate ...
First Order Reaction Half-life The half-life of a first-order reaction is independent of the concentration of reactants This means that despite the concentrations of the reactants decreasing during...
Kinetics: Calculations Order of reaction The order of reaction shows how the concentration of a reactant affects the rate of reaction Rate = k [A]m [B]n When m or n is zero = the concentration of t...
Kinetics: Basics The rate of reaction refers to the change in the amount or concentration of a reactant or product per unit time and can be found by: Measuring the decrease in the concentration of ...
Partition Coefficient & Calculations The partition coefficient (Kpc) is the ratio of the concentrations of a solute in two different immiscible solvents in contact with each other when equilibr...
