MCQ
${K_2}C{r_2}{O_7}\xrightarrow{\Delta }A + B + C$
$B$ is green colored compound then it would be
- A$K_2CrO_4$
- ✓$Cr_2O_3$
- C$CrO_3$
- D$O_2$
✓
Answer
Correct option: B.
$Cr_2O_3$
b
$\begin{gathered}
{K_2}C{r_2}{O_7} \to {K_2}Cr{O_4} + C{r_2}{O_3} + {O_2} \hfill \\
\,\,\,\,\,{\text{Green Color compound}} \hfill \\
\end{gathered} $
$\begin{gathered}
{K_2}C{r_2}{O_7} \to {K_2}Cr{O_4} + C{r_2}{O_3} + {O_2} \hfill \\
\,\,\,\,\,{\text{Green Color compound}} \hfill \\
\end{gathered} $
