Chemical equilibrium<span> is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. </span><span>Or, we can say that in chemical equilibrium the ratio between the concentration of the reactants and the products is constant.</span><span> Chemical equilibrium is a result state when </span><span>the forward reaction proceeds at the same rate as the reverse reaction. </span><span>Different reactions have different equilibrium.</span>
From the equation; 4 Al + 3 O2 = 2 Al2O3 The mole ratio of Oxygen is to Aluminium hydroxide is 3:2. Therefore; moles of Al2O3 is (0.5/3 )× 2 = 0.333 moles Therefore; The moles of aluminium oxide will be 0.333 moles
