The reaction of ethanol with ethanoic acid produces ethyl ethanoate and water. C,H;OH(1) + CH,COOH(1) - CH,COOC,H,(1) + H,0(1) A student suggested that the yield of ethyl ethanoate, CH,COOC,H, could be increased by removing the water as it was formed. Explain, using the idea of K, why this suggestion is sensible.
