When calculating the work done in a nuclear fission reactionwe must use the following formula: W=ΔE Where work is defined as the change in energy within the reaction and energy is defined as E=Δmc2 3.0 × 10 8 m / s To calculate the energy of the reaction, we must first calculat...
If the total internal energy, total pressure and the total volume of a phenomenon are given, then by using the sum of the energy and the product of the pressure and volume is generally used to calculate the enthalpy. The general expression of the enthalpy is shown below, ...
How do you calculate dosing interval based on half-life? The half-life of a first-order reaction is 1.5 hours. How much time is needed for 94% of the reactant to change to product? Consider the following reaction: A B. The reaction is first order for A. If the rate constant for th...
The reaction rate, or the speed that the reaction happens at, is written as the change in concentration of a reactant or product per change in time as shown above. In order to calculate this experimentally you have to monitor either the concentration of the reactant or product as a functio...
In an example of a simple chemical reaction, one atom of potassium (K) can react with one atom of chlorine (Cl) to form a molecule of potassium chloride (KCl) with nothing left over. But this is not because potassium atoms and chlorine atoms have the same mass. Instead, it is because...
Energy diagrams areused to represent the change in energy for the molecules involved in a chemical reaction. The free energy is measured along the y-axis, and the reaction coordinate is plotted on the x-axis. The reaction coordinate indicates the progress of the conversion of reactants to pro...
Potential energy transfers to kinetic energy when a rock falls from a ledge. When the rock hits the ground, its kinetic energy is transformed into thermal energy. In a combustion reaction, chemical energy is transformed into thermal energy. In reactions that change molecular makeup, energy is ei...

How does mass change during a chemical reaction? Building Blocks Of Matter: All matter is made up of tiny building blocks called atoms. Atoms are bonded together to form molecules and compounds, which make up everything that exists in the universe. The amount of matter in a substance is dir...
How do you calculate free energy? Gibbs free energy, denoted G, combines enthalpy and entropy into a single value. The change in free energy, ΔG, isequal to the sum of the enthalpy plus the product of the temperature and entropy of the system. ...
