... It may be useful to draw a carbon atom and one other atom to illustrate the difference between elements. You can use the carbon atom to show its atomic number and mass and then elicit the atomic number and mass of the other atom. Finally, draw an isotope of carbon (perhaps carbon 14) and one of the ...

... Go therefore describes this reaction only when all three components are present at 1 atm pressure. The sign of Go tells us the direction in which the reaction has to shift to come to equilibrium. The fact that Go is negative for this reaction at 25oC means that a system under standard-state conditio ...

... Spontaneity of Chemical Reactions When the valve between the two bulbs is opened [Fig 12.1 (b)], the two gases mix spontaneously. The mixing of gases continues until the partial pressure of each gas becomes equal to 0.5 bar in each bulb i.e., the equilibrium is attained. We know from experience tha ...

... When solutions are involved in a reaction, only some of the ions present are usually involved. Other ions may be present, but they are still in the solution at the end of the reaction, unchanged by the chemical process. These ions are called spectator ions and are best left out of the balanced equat ...

Chemical equilibrium
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s). Such a state is known as dynamic equilibrium.
