Select the false statement. Which of the given statements is not a reason why reactions are performed under reflux? Refluxing allows thermally unstable reactants to react faster without decomposition. Refluxing prevents the loss of solvent. Refluxing increases the reaction rate. Refluxing allows the reaction to proceed under stable, controlled conditions for long periods of time.

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 :

the correct answer is:

a. formation of precipitation
