1. 1.Equal amounts of ethanol and ethnic acid were mixed and allowed to reach equilibrium at room temperature. 60% of the acid esterfied. Calculate Kc for the reaction.
The equation is: C2H5OH +CH3CO2H--> CH3CO2C2H5+ H2O

Say that 1 mol of ethanol and 1 mole of acid were used. Then the equilibrium amounts are: 0.40 mol ethanol, 0.40 mol acid, 0.60 mol ester. Concentration = amount/volume. Now put the values of concentration into the expression for Kc.
