0.75 moles of a solid

{A_4}

and 2 moles of

{O_2}(g)

are heated in a sealed vessel, completely using up the reactants and produces only one compound. It is found that when the temperature is used to initial temperature, the contents of the vessel exhibit a pressure equal to

\frac{1}{2}

of the original pressure. The formula of the product will be

View answer and explanation

Correct option: C

{A_3}{O_4}

Option C (

{A_3}{O_4}

) is correct because the stoichiometry of the reaction and the pressure change indicate that 3 moles of

{A_4}

react with 8 moles of

{O_2}

to produce 4 moles of

{A_3}{O_4}
