One mole of  ${\text{FeC}}_{\text{2}}{\text{O}}_{\text{4}}$ is separately oxidized by ${\text{KMnO}}_{\text{4}}{\text{\hspace{0.17em}and\hspace{0.17em}K}}_{\text{2}}{\text{Cr}}_{\text{2}}{\text{O}}_{\text{7}}$ in acid medium into $F{e}^{3+}$ ions and ${\text{CO}}_{\text{2}}$ molecules. Which statements are true 

Equivalent weight of ${\text{FeC}}_{\text{2}}{\text{O}}_{\text{4}}$ is 1/3^rd  of its formula weight

${\text{FeC}}_{\text{2}}{\text{O}}_{\text{4}}$ undergoes disproportionation

The ratio of number of equivalents of ${\text{KMnO}}_{\text{4}}{\text{\hspace{0.17em}and\hspace{0.17em}K}}_{\text{2}}{\text{Cr}}_{\text{2}}{\text{O}}_{\text{7}}$ required is 1:1

The mole ratio of ${\text{KMnO}}_{\text{4}}{\text{\hspace{0.17em}and\hspace{0.17em}K}}_{\text{2}}{\text{Cr}}_{\text{2}}{\text{O}}_{\text{7}}$ required is 6:5
