Ответ:
answer: the value of enthalpy change will be -152.80 kj.
solution:
pressure = 1atm , temperature =
= 298 k ![)0^oc=273kelvins](/tex.php?f=)0^oc=273kelvins)
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 :
