How many moles of potassium chlorate to be heated to produce `5.6` litre oxygen at `STP` ?

Text Solution

Verified by Experts

`{:(,2KClO_(3)rarr,2KCl,+,3O_(2)),("mole ratio for reaction",2"mole",2"mole",,3"mole"):}`
`3xx22.4` litre `O_(2)` is formed by `2` mole `KClO_(3)`
`:. 5.6` litre `O_(2)` is formed by `(2xx5.6)/(3xx22.4)= 1//6` mole `KClO_(3)`
