The hydration of Ethylene to alcohol <strong>is</strong> given by C2H2 + H2O C2H5OH<br />
Temperature 0 C 145 6.8 x 10 -2<br />
Equilibrium Constant 320 1.9 x 10 -3<br />
The heat capacity data f<strong>or</strong> the component can be<br />
represented by Cp = a + bT where T <strong>is</strong> in kelvin<br />
and Cp <strong>is</strong> in cal / g mol 0 C<br />
Develop general expression f<strong>or</strong> the equilibrium constant and standard Gibb’s free<br />
