Explanation:

The reaction:

SO₃(g) + SCl₂=> SOCl₂(l) + SO₂(g)

parameters                                                                                                                    

                           SO₃(g)       SCl₂(l)       SOCl₂(l)          SO₂(g)

ΔH°f(kJ/mol)          -396           -50.0         -245.6          -296.8

S°(J/mol.k)            256.7          184               -                 248.1

ΔG°r = -75.2 kJ

a).

S° of SOCl₂

ΔH°rxn = ΔH°f[Product] - ΔH°f[reactant]

ΔH°rxn = [1 mole * ΔH°f(SOCl2(l)) + 1 mol * ΔH°f(SO2(g))] - [1 mol *ΔH°f(SO3(g)) + 1 mole ΔH°f(SCl2(l))]

ΔH°rxn = [1 mole * -245.6kJ/mol + 1 mol * -296.8kJ/mol] - [1 mol * -396kJ/mol + 1 mole * -50kJ/mol]

ΔH°rxn = -96.4 kJ

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

explanation:

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 :
