If the temperature is raised which direction will the equilibrium shift? 1 N,+ 3 H2 2 NH3 + heat

A) Right towards the product to remove the added heat
B)Left towards the reactants to remove the added heat.
C) Right towards the product to replace the removed heat
D)Left towards the reactants to replace the removed heat.

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 :
