D all &#39;a&#39;, &#39;b&#39; &amp; &#39;c&#39;. As per Gilliland&#39;s equation, the diffusivity is directly proportional to &#39;T^1.5&#39; and inversely proportional to &#39;P&#39;. Gilliland&#39;s equation describes the diffusivity (&#119863;D) of a gas mixture and is given by: &#119863;=0.001858&#119879;1.5&#119875;D=P0.001858T1.5​ Where: &#119863;D is the diffusivity of the gas mixture. &#119879;T is the absolute temperature in Kelvin. &#119875;P is the pressure in atm. According to Gilliland&#39;s equation: Diffusivity is directly proportional to the square root of temperature raised to the power of 1.5 (&#119879;1.5T1.5). This means that as temperature increases, the diffusivity increases. Diffusivity is inversely proportional to pressure (&#39;P&#39;). This means that as pressure increases, the diffusivity decreases. However, Gilliland&#39;s equation does not directly account for molecular volume and molecular weight of components. Therefore, the correct answer is directly proportional to &#39;T^1.5&#39; and inversely proportional to &#39;P&#39;.
