Explanation:
Standard formation of an substance is defined as formation of one mole of substance from its constituting elements.
Chromium(III) nitrate is composed of chromium, nitrogen and three oxygen atoms.
[tex]2Cr(s)+3N_2(g)+9O_2\rightarrow 2Cr(NO_3)_3(s)[/tex]
A balanced chemical equation for the standard formation reaction of solid chromium(III) nitrate
[tex]Cr(s)+\frac{3}{2}N_2(g)+\frac{9}{2}O_2\rightarrow Cr(NO_3)_3(s)[/tex]
The balanced Standard formation reaction reaction will be
[tex]\rm \bold { Cr(s) + \frac{3}{2} N_2(g)+\frac{9}{2} O_2(g) \rightarrow Cr (NO_3)_3(s)}[/tex]
Standard formation reaction:
It is defined as formation of one mole of substance from its constituting elements.
[tex]\rm \bold { 2Cr(s) + 3N_2(g)+9 O_2(g) \rightarrow 2Cr (NO_3)_3(s)}[/tex]
Here, reactants combined to form 2 moles of Chromium(iii) nitrate,
Hence, half of the concentration of reactant will form 1 mole product
Therefore, the balanced reaction will be
[tex]\rm \bold { Cr(s) + \frac{3}{2} N_2(g)+\frac{9}{2} O_2(g) \rightarrow Cr (NO_3)_3(s)}[/tex]
