1) Starting from $1.0\;mol$ of a carboxylic acid A and $1.0\;mol$ of an alcohol B , we find that the yield of the esterification is $0.80$. Calculate the quantities of all reactants and products at equilibrium and the equilibrium constant. 2) Calculate the yield in relation to alcohol, if we start from $2.0\;mol$ of A and $1.0\;$ mol of B. 3) Compare 1) and 2) and interpret!
