The following table contains data for the equilibrium reaction

CH3COOH(g)+ C2H5OH(g)↔ CH3COOC2H5(g)+ H2O(g)

T = 100oC.

Each row in the table represents a different experiment (diffferent intial concentrations).

Initial concentration Equilibrium concentration

--------------------------- -------------------------

[CH3COOH(g)] [C2H5OH(g)] [CH3COOC2H5(g)]
mol/L mol/L mol/L


1.00 (not given) 0.166

1.00 (not given) 0.616

1.00 (not given) 0.967

What is [H2O(g)] at equilibrium in the third experiment (third row of values) ?

HINT 1 : You solve this problem by inspection of the table values. It is helpful to write out the reaction and note the changes in reactants and products, in terms of x. Then fill in one or more values of x that are given above. But you do not need to do any calculations.

HINT 2 : The initial concentrations of the products are each zero mole/L .
