Consider the reaction shown below:

Which of the following statements is false? [Atomic mass of zinc= 65.4]

The conversion of ${\mathrm{CrO}}_4^{2-}$ into ${\mathrm{Cr}}_2{\mathrm{O}}_7^{2-}$ is not a redox reaction

is not a redox reaction ${\mathrm{Cr}}_0{\mathrm{O}}_7^{2-}+14{\mathrm{H}}^{+}+6{\mathrm{Fe}}^{2+}⟶6 {\mathrm{Fe}}^{3+}+2{\mathrm{Cr}}^{3+}+7{\mathrm{H}}_2\mathrm{O}$ correctly describes the reduction of ${\mathrm{Cr}}_2{\mathrm{O}}_7^{2-}$ by acidified ${\mathrm{FeSO}}_4$.

Silver chromate (VJ) has the formula ${\mathrm{Ag}}_2{\mathrm{CrO}}_4$

The minimum mass of zinc required to reduce 0.1 mole of ${\mathrm{Cr}}^{3+}$ to ${\mathrm{Cr}}^{2+}$ is 6.54 g.
