For the reaction : H_(2)(g) + (1)/(2)O_(2)(g) rarr H_(2)O(l), Delta H = - 68 kcalmol^(-1) The heat change for the decomposition of 7.2 g of water is

Answer»

`13.6 KCAL`
`27.2 kcal`
`54.4 kcal`
`-34 kcal`

Solution :HEAT change for the decomposition of 1 MOLE or 18 g water = 68 kcal
Heat change for the decomposition of 7.2 g of water = `(68 XX 7.2)/(18) = 27.2 kcal`
