In the reaction aa + bb cc + dd, the lowercase letters represent:

Explanation:

When we write a chemical reaction equation, then entries on the left hand side represent the reactants and entries on the right hand side represent the products.

Whereas in the equation, .

The lowercase letters represent the coefficients in the given balanced chemical reaction equation.

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 :
