What is coal? Coal is a fossil fuel and is the altered remains of prehistoric vegetation that originally accumulated in swamps and peat bogs. The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago. All living plants store solar energy through a process known as photosynthesis.
Dynamic equilibrium. Definition. noun. A system in a steady state since forward reaction and backward reaction occur at the same rate. Supplement. In a dynamic equilibrium, the rate of loss is equal to the rate of gain. Dynamic equilibrium is applied in thermodynamics for systems involving reversible reactions.
The shape of the equilibrium curve depends upon the reaction mechanism and can be used. to decide between different equilibrium models. Equilibrium constants. An equilibrium constant, designated by a upper case K, is the ratio of the equilibrium. concentrations of reaction products to reactants or vice versa. For the bimolecular reaction, A+B â AB, we can define an equilibrium dissociation. constant (Kd) or an equilibrium association constant (Ka), which are reciprocally.
