What is the change in enthalpy for the following reaction? 
Tju [1.3M]

The given chemical reaction is:

2H_{2}O_{2}(aq)---> 2H_{2}O(l)+O_{2}(g)

The standard heats of formation of H_{2}O and H_{2}O_{2} are:

ΔH_{f}^{0}(H_{2}O) = -285.8kJ/mol[/tex]

ΔH_{f}^{0}(H_{2}O_{2}) = -187.6 kJ/mol[/tex]

Calculating the change in heat:

ΔH^{0}_{reaction)=∑ΔH_{f}^{0}(products)-∑ΔH_{f}^{0}(reactants)

                         = [{2 * (-285.8 kJ/mol)} -{2*(-187.6 kJ/mol)}]

                          = -196.4 kJ/mol

Therefore, the change in enthalpy for the given reaction is -196.4 kJ/mol
