18 cm^3 of carbon (ii) oxide are spartad with 18 cm^3 of oxygen . if all volume of gases are measure at s. t.p. calculate the volume of residual gases after sparking ​

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 :

i'm pretty sure its b i might be wrong though!
