Solid sodium chloride is added to a beaker containing 100.0 mL of water until the solution is saturated. Solid sodium chloride is visible at the bottom of the beaker. The The process can be represented by:
Na+ (aq) + C7- (aq) = NaCl(s)
A chemist adds concentrated hydrochloric acid to the saturated solution. What will the chemist observe?

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 :
