Estimate the fugacity of a ternary gas mixture consisting of \(25 \mathrm{~mol}\) per cent hydrogen (component 1), \(35 \mathrm{~mol}\) per cent of nitrogen (component 2), and \(40 \mathrm{~mol}\) per cent of argon (component 3). We are given that at \(150^{\circ} \mathrm{C}\) and \(60 \mathrm{bar}\), the fugacity coefficients of components 1,2 , and 3 are \(0.7,0.85\), and 0.90 respectively.
