How much steam is required and what is the final conc of H2SO4 in tank?

Please see the attached file for the fully formatted problem(s). An insulated tank, open to the atmosphere, contains 1,500 (lbm) of 40-wt-% sulfuric acid at 60oF. It is heated to 180oF by injection of live saturated steam at 1 atm, which fully condenses in the process. How much steam is required, and what is the final concentration of H2SO4 in the tank? [TABLE]

How much steam is required for each pound mass of entering acid?

Please see the attached file for the fully formatted problem(s). Saturated steam at 40 psia is throttled to 1 atm and mixed adiabatically with (and condensed by) 45-wt-% sulfuric acid at 80oF in a flow process that raises the temperature of the acid to 160oF. How much steam is required for each pound mass of entering acid, and what is the concentration of the hot acid? [CHART]

Equilibrium Concentrations at a Certain Temperature and Pressure: Varying Reaction Coefficients

Please see the attached file for the fully formatted problem(s). Equilibrium Concentrations at a Certain Temperature and Pressure: Varying Reaction Coefficients 13.10. Peter, Paul, and Mary, members of a thermodynamics class, are asked to find the equilibrium composition at a particular T and P and for given initial amounts of reactants for the following gas-phase reaction: 2NH3 + 3NO -> 3H2O + 5/2 N2 (A) Each solves the problem correctly in a different way. Mary bases her solution on reaction (A) as written. Paul, who prefers whole numbers, multiplies reaction (A) by 2: 4NH3 + 6N0 -> 6H20 + 5N2 (B) Peter, who usually does things backward, deals with the reaction: 3H2O + 5/2 N2 ->... click for more
