Find the fugacity coefficient at 1 bar, 5 bar, and 10 bar for a gas that follows the equation of state PV = RT(1 – 0.00513 P), where P is pressure in bar
Derive the equation for determination of fugacity of pure gases using any two methods.
For a binary solution consider M1 and M2 are properties of component 1 and component 2 in a solution. Derive equations to calculate partial properties of component 1 and component 2 in a solution.
At 303 K, the vapour pressures of benzene (A) and toluene (B) are 15.75 kPa and 4.89 kPa respectively. Determine the partial pressures and weight composition of the vapour in equilibrium with a liquid mixture consisting of equal weights of the two component
Prove that for a multi component system, chemical potential of each component is the same in all phases.
Define azeotrope and explain maximum and minimum boiling azeotrope with a neat diagram.
List out different methods to determine thermodynamic consistency of VLE data and explain any one in detail.
The water–gas shift reaction, CO(g) + H2O(g) CO2(g) + H2(g) takes place at 373 K. The equilibrium constant KP for this reaction at 537 K = 9.8 x 10–4. The heats of formation at 298 K are: CO = –110,525 J/mol, CO2 = –393,509 J/mol, H2O = –241,818 J/mol. Calculate the equilibrium constant at 1000 K.
What is the effect of temperature on equilibrium constant? Using Van’t Hoff equation predict the effect of increasing temperature on endothermic and exothermic reactions.
CH4+ H2O→ CO+3H2……….. (1)CH4 + 2H2O→ CO2 +4H2 …….(2)If 2mol CH4 and 3mol H2O are initially present, Compute the mole fraction of theproduct gases for ε1= 0.25 and ε2=0.5What do you mean by the ‘extent of reaction’? How is it related to the mole fraction of the species in the reaction mixture?
Calculate standard Gibbs free energy change and equilibrium constant at 700 K for the reaction: N2(g) + 3H2(g) 2NH3(g) Given that the standard heat of formation and standard free energy of formation of NH3 at 298 K to be – 46100 J/mol and – 16500 J/mol respectively. The specific heat (J/mol K) as a function of temperature for nitrogen, hydrogen and ammonia are as given below. CP, N2 = 27.27 + 4.93 ´ 10 – 3 T CP, H2 = 27.01 + 3.51 ´ 10 – 3 T CP, NH3 = 29.75 + 25.11 ´ 10 – 3 T
