Acc<strong>or</strong>ding to Gibbs Duhem equation both slopes must have oppsite sign then only the<br />
data <strong>is</strong> cons<strong>is</strong>tent, otherw<strong>is</strong>e it <strong>is</strong> incons<strong>is</strong>tent.<br />
F<strong>or</strong> the data to be cons<strong>is</strong>tent it h<strong>as</strong> sat<strong>is</strong>fy the following condition.<br />
1. If one of ln curves h<strong>as</strong> maximum at certain concentration and the other curve<br />
2.<br />
should be minimum at same composition.<br />
If there <strong>is</strong> no maximum <strong>or</strong> minimum point both must have + ue <strong>or</strong> –ue on entire<br />
range.<br />
