4. When Ted earned his driver's license, he wanted his first solo drive to be to a friend's house. Previously, Ted had always biked to his friend's house and was able to cut though the yards an a park in order to bike
there in a straight line. In his car, however, Ted had no choice but to follow the streets. As a result, he
traveled 6 miles east, 6 miles south, and 2 more miles east. How much shorter, in miles, is Ted's bike route
than his car route?

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 :

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

it is reliable if two scientists recorded it
