Step 1:H2O2 + I^-^ = H2O + OI^-^
step 2: H2O2 + OI^-^ = H2O + O2 + I^-^
What is the equation for the overall reaction? I am not sure how to do this since there are two equations.
Complete the rate law for the overall reaction. I know how to do this one but I am not sure of the equation for the first question.
To find the overall reaction equation, you need to add the two given equations together. By doing so, the I^- ions on both sides of the equation will cancel out, leaving H2O2 on the reactant side and H2O and O2 on the product side:
H2O2 + I^- = H2O + OI^-
H2O2 + OI^- = H2O + O2 + I^-
-----------------------------
2H2O2 = 2H2O + O2
Therefore, the overall reaction equation is
2H2O2 = 2H2O + O2
