... The rms speeds are inversely proportional to the square root of mass, so the ratio of Ar speed / He speed is ≈ sqrt (4/40) ≈ 0.3 (b) If Ar, He, and Xe are mixed with equal partial pressures in a gas sample, which will effuse most rapidly through a small hole in the container ? Explain briefly. He. E ...

... At equilibrium, the rate of the forward reaction is the same as the rate of the reverse reaction. At equilibrium, the number of moles of SO3 present in the reaction vessel will always be the same as the number of moles of SO2 present, regardless of the temperature. Changing the volume of the vessel ...

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.
