PP HEL ME WITH THIS QUESTION BRAINLIEST PLUS 20 POINTS Stress was added to the following reaction and this was the result: As4O6 + 6C <-> As4 + 6CO

The equilibrium shifted to the right and the reverse reaction decreased.

Select all factors that would have caused this observation.
Question 3 options:

CO was added to the system

As4 was added to the system

As4 was removed from the system

As4O6 was removed

a chemical reaction happens

explanation:

answer: the enthalpy of the overall chemical reaction is +87.88 kj or +88 kj.

according to hess's law, the overall enthalpy of a reaction is the difference between the sum of enthalpy values of all the products and the sum of enthalpy values of all the reactants.

δh(reaction) = ∑nδh(products) - ∑nδh(reactants)

δh(reaction) = [δh +δh] - [δh]

δh(reaction) = [1(-287.02) + 1(0) ] - [1(-374.9)] kj = +87.88 kj

here, δh (pcl3) = -287.02 kj, δh(cl2) = 0, δh(pcl5) = -374.9 kj

therefore, enthalpy of the overall reaction is +87.88 kj or +88 kj.
