$2Li_2O \xrightarrow[673 \ K]{	ext{heat}} Li_2O_2 + 2Li$

Vedclass · Answer

(A) The reaction $2M_2O \xrightarrow[673 \ K]{	ext{heat}} M_2O_2 + 2M$ is generally not a standard method for preparing peroxides of alkali metals.Specifically,$Li$ is the smallest alkali metal and its oxide $Li_2O$ is very stable.$Li$ does not form a peroxide $(Li_2O_2)$ under these conditions; it primarily forms the monoxide $Li_2O$ upon combustion in excess air.Therefore,the reaction shown in option $A$ is chemically incorrect.

Which of the following reactions is not correct?
