20 ml of acetic acid reacts with 20 ml of ethyl alcohol to form ethyl acetate. The density of acid and alcohol are 1 g/ml and 0.7 g/ml respectively. The limiting reagent in this reaction is :

Answer»

ACETIC acid
Ethyl ALCOHOL
Acetic acid and ethyl alcohol
Ester.

Solution :`CH_3COOH + C_2H_5OH to CH_3COOC_2H_5 + H_2O`
moles of `CH_3COOH= (20 xx 1)/(60) = 0.333 `moles
molesof `C_2H_5OH = (20 xx 0.7)/(46) = 0.304` moles
` therefore ` Ethyl alcohol `(C_2H_5OH)` is the LIMITING reagent .
