Question #4a385

May 1, 2015

Hydrogen peroxide decomposes to give water and oxygen according to the balanced chemical equation

$2 {H}_{2} {O}_{2 \left(a q\right)} \to 2 {H}_{2} {O}_{\left(l\right)} + {O}_{2 \left(g\right)}$

Because hydrogen peroxide is unstable from a thermodynamic point of view, it will undergo a decompositon reaction to produce water and oxygen.

If the reaction is not catalyzed, the decompopsition will occur at a vey slow rate.
