k1 Hexane can equilibrate to methyl-substituted pentanes and methylcyclpentane according to: hexane \stackrel{k_1}{\rightleftharpoons} methylcyclopentane + H2 k-1 k2 hexane \stackrel{k_2}{\rightleftharpoons} 2-methylpentane k-2 Component n-hexane methylcyclopentane 2-methylpentane hydrogen f ?H600K (kcal/mol) f ?G600 K (kcal/mol) -46.10 43.02 -31.69 45.76 -47.63 42.39 0 0 in which ?H600 K and ?G600 K are the heats of formation and the Gibbs free energy of formation of the compounds at 600 K from the elements, respectively. Find the temperature where equal amounts of methylcyclopentane, and 2-methylpentane form if pure hexane is allowed to equilibrate at 1 atm total pressure. Also, find the composition of the mixture at this temperature. At this condition, the hydrocarbons are gases.
