Into a 1000-gal tank, initially filled with 100 gal of fresh water (density = 62.4 lb/ft), salt water containing 1.92 lb/gal of salt flows at a fixed rate of 4.0 gpm. the density of the incoming solution is 71.807 lb/ft? . the solution, kept uniform by stirring, flows out at a fixed rate of 19.2 lb/min. how many pounds of salt will there be in the tank at the end of 90 minutes? 1 ft = 7.48 gal.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

idk what is it? is this a question that you know the answer or u dont
