What would cause entropy to decrease in a reaction?
A. The products gaining more mobility than the reactants
B. The products becoming more ordered than the reactants
C. The products becoming more randomly arranged
D. The products spreading out more than the reactants

the product of the pressure and volume is also constant

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 :
