Webtemperatures is shown in fig. 2a.and 2b The experimental values of both the excess parameters were fitted to the Redlich - Kister equation [M. I. Aralgappi et al, 1991] to obtain Bj coefficients at different temperatures. Using these B j values excess parameters at various concentrations were calculated and used to draw the smooth curves. WebThe excess molar volume was correlated by Redlich and Kister (1948) as shown in Eq.
