The bird nothing changes bobs faster а. с. bobs slower b. d. stops bobbing 21. Air at 2-bar pressure dissolves in the liquid solvent at equilibrium. Oxygen has a higher solubility than N2, so the O2 concentration is twice N, the concentration. The gas-phase equilibrium mixture is 20% O2, 80% N2. Which is correct about the fugacities? air solvent fo2 = fN2 fN2 = 4fo2 fo2 = 2fN2 d. none of the choices а. b. fo2 < fh20="" е.="" с.="" 22.="" when="" comparing="" steam="" at="" 100°c="" to="" water="" at="" 100°c,="" steam="" has="" a="" higher="" enthalpy,="" and="" lower="" entropy,="" lower="" gibbs="" free="" energy="" the="" same="" entropy,="" the="" same="" gibbs="" free="" energy="" none="" of="" the="" choices="" d.="" higher="" entropy,="" the="" same="" gibbs="" free="" energy="" higher="" entropy,="" higher="" gibbs="" free="" energy="" а.="" b.="" е.="">
