Which of the following best describes what led to london’s “killer fog” in 1952? a. pollution from the air contaminated the water supply which is what killed people. b. millions of coal fires and stagnant air caused toxic fumes to build up in the air. c. poor city design led to faulty ventilation in houses. d. soot from forest and wildfires in the surrounding areas blew over the city.

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 :
