Experimentally Determining of the Order of a Chemical Reaction

The rate of a chemical reaction depends upon the rate constant and the concentrations of the reagents and products each raised to a power, the......

Experimental Arrhenius Plot: Mathematical Example

k = Ae-(Ea/RT) Firstly, using the following experimental data for the rate constants and temperatures draw a graph of ln(k/s-1) versus (1/T) x (103 K)......

What is Radioactive Decay?

Radioactive decay is a first-order chemical reaction which follows an exponential decay in the reactant, the radioactive element. Starting with an original number of radioactive......

How Chemical Work at Constant Pressure?

Chemical Work at Constant Pressure The ability of a chemical reaction to perform work at a constant pressure is given by the Gibbs energy AG°......

Explain Nernst Equation

The following redox chemical reaction Zn(s) + Cu2+ → Zn2+ +Cu(s) can be made into an electrochemical cell to derive electrical energy, below Figure. The......

Explain Arrhenius Equation

Question 1: The rate constant k of a chemical reaction increases with the absolute temperature T. This increase follows the equation below which is called......

First Order Kinetics: Mathematical Example

Question 1: The concentration of the reactant in a first-order chemical reaction decreases with time as it is consumed to form products and the concentration......

Explain Acid Base Equilibrium

Question 1: The molar concentration of OH– ions in a certain solution is 1.04 x 10-5 mol L-1. Calculate the pOH and then the pH of......

What is Logarithm?

bc = a,   b must be greater than 1 then c = logb (a) We say that c is the logarithm to the base b......
