Ascientist wants to create a drug that will kill cancer cells upon absorption in the intestines. in order for the drug to work effectively, it must not be absorbed until it reaches the intestines. the scientist tests different acidities of compounds to determine which combination will keep the drug intact until it reaches the intestines. what part of the engineering process is the scientist engaged in?

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 :
