WebWe can use the DHLL to estimate the activity coefficients of ions in solution. WebActivity Coefficient is a coefficient used in thermodynamics to explain deviations from ideal behaviour in a combination of synthetic substances. In an ideal mixture, the tiny interactions between each pair of species are equal (or equivalent, with zero solution enthalpy and volume changes during mixing), resulting in the mixture. Hence, the properties of the …

WebHuckel’s rule is a criterion used to characterise the aromaticity of a compound. If a compound obeys Huckel’s rule of aromaticity, it is classified as an aromatic compound. In contrast, if a compound doesn’t follow Huckel’s rule of aromaticity, it can either be anti-aromatic or non-aromatic. Huckel states that a compound will be aromatic if,
