Question

the equilibrium A+4B=AB4 is attained by mixing equal moles of A and B in a one litre vessel.then at equilibrium

Answer 1

The number of moles at equilibrium will be determined by the limiting reactant. If A and B react in the ratio 1:4 then we need to find the product formed by each reactant.

$mol AB_4=1 mol A \times\frac{1molAB_4}{1 mol A}= 1 mol A$

$mol AB_4= 1 mol B \times \frac{1 mol AB_4}{4 mol B} = 0.25 mol AB_4$

B is the limiting reactant since it gives less product, hence at equilibrium all available moles of B will have been consumed,  0.75 mol of A remains unreacted and 0.25 mol $AB_4$ is formed.
