Explain 1 s Electron of the Hydrogen Atom with Integration

The probability P that an electron is a distance r from the nucleus is called the radial distribution function. The hydrogen atom’s is electron radial......

Integration Quantum Mechanics of Conjugated Polyene Molecule

A polyene molecule is a linear hydrocarbon chain of alternating single and double bonded C-atoms. Polyene molecules are important in biological processes and below Figure......

Enthalpy of Molecule and Temperature Changes with Integration

The enthalpy of a molecule, H, changes by dH when the temperature, T, changes by dT and the change is commonly given as a polynomial......

Ideal Gas Expansion with Integration

We have one mole of ideal gas at an initial volume of 4.90×103 cm3 which expands to a final volume of 2.45×104 cm3 at a......

Describe Expanding Gas and Thermodynamic Work

In Chemistry it is very common to have gases being formed, reacting, compressed or expanding. A simple way of understanding such processes is to begin......

Explain Second-Order Chemical Reactions with Intregration

If the overall (or stoichiometric) reaction is two molecules of A reacting to give products 2A → P with rate constant k then for some......

Explain Radioactive Decay with Integration

The decay of a radioactive element A → P has a rate constant k. Radioactive decay is a first-order chemical reaction with [A] and t......

Explain Consecutive Chemical Reactions with a Rate Determining Step

[B] = [A]0 [k1 /(k2 – k1) (e-k1t – e-k2t) By consideration of each of the terms of the equation find approximate expressions for [B]......

Consecutive Chemical Reactions: the Steady State Approximation

[B] = [A]0 [k1 /(k2 – k1) (e-k1t – e-k2t) By consideration of each of the terms in the equation show that if k2 is......

Describe Consecutive Chemical Reactions

Two chemical reactions consecutively follow on from one another. Consecutive reactions are generally very common in biochemistry and organic chemistry.  K1     k2 A → B......

Explain Differentiation of the Arrhenius Equation

The rate constant k for a chemical reaction is related to the temperature T by the Arrhenius equation. k = Ae– (Ea/RT) Where A and......

How to Change in pH?

The pH of a solution in which the hydrogen ion concentration is [H] is defined by: pH = – log[H+] Firstly, show that d(pH)/d[H+] arising......
