The three elementary reactions below occur in aqueous acidic solution. Step 1 H2_2O2_2 + I−^- → HOI + OH−^- Step 2 HOI + H+^+ + I−^- → I2_2 + H2_2O Step 3 H+^+ + OH−^- → H2_2O Which of the following is the overall balanced chemical equation implied by this mechanism? a) H2_2O2_2 + I−^- + H+^+ \rightarrow I2_2 + H2_2O b) H2_2O2_2 + 2 I−^- \rightarrow I2_2 + 2 OH−^- c) H2_2O2_2 + 2 I−^- + 2 H+^+ \rightarrow I2_2 + 2 H2_2O d) 2 H2_2O2_2 + 2 I−^- \rightarrow I2_2 + 2 H2_2O + O2_2
