A plane traveled for 2 hours at a speed of 1200 km/hr. What distance did it travel? 2000 km
600 km
1200 km
2400 km

2400 km

Explanation: 1200 km/hr • 2 hr = 2400 km

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 :
