The Mechanism for the Reaction 2H₂O₂(aq) $\rightarrow$ 2H₂O( ) + O₂(g) in the Presence of I^-(aq)

The mechanism for the reaction 2H₂O₂(aq) $\rightarrow$ 2H₂O( ) + O₂(g) in the presence of I^-(aq) is proposed to be Step 1: H₂O₂(aq) + I^-(aq) $\rightarrow$ H₂O( 11eff76a_6ab5_5f7b_a45e_c74b4a506edc_TB3833_00 ) + OI^-(aq)
(slow)
Step 2: H₂O₂(aq) + OI^-(aq) $\rightarrow$ H₂O( 11eff76a_6ab5_5f7b_a45e_c74b4a506edc_TB3833_00 ) + O₂(g) + I^-(aq)

What is the rate law for the overall reaction?

A) Rate = k[H₂O₂]
B) Rate = k[H₂O₂]²
C) Rate = k[H₂O₂][I^-]
D) Rate = k[H₂O₂][OI^-]
E) Rate = k[H₂O₂]²[I^-]/[H₂O]
