`H_(2)O_(2)` decomposes in an aqueous solution to give `H_(2)O` and oxygen gas. The rate constant of disappearance is `2xx10^(-2) sec^(-1).` Calculate the amount of heat liberated per second initially from `0.5 L "of" 2M H_(2)O_(2)` solution (in kJ)
`H_(2)O_(2) (aq) to H_(2)O (l) + 1/2 O_(2) (g)`
`DeltaH= 100 kJ//"mole"`
