C12H22O11→12C +11 H2O
The type of reaction above is a decomposition reaction.
Explanation
A decomposition reaction is type of reaction that involve breaking down compound into smaller compounds or individual element.
Decomposition reaction mostly requires energy in form of heat which break down compound.
C12H22O11 is breakdown down into 12 C and 11 H2O therefore the reaction above is a decomposition reaction.
