The complete chemical reaction of aqueous Sodium sulfate and aqueous Barium nitrate is

$Na_{2} SO_{4} (aq) + Ba(NO_3)_2(aq) -\ \textgreater \ BaSO_4(s) + 2NaNO_3(aq)$

The right side and the left side of the reaction have equal number of elements, therefore it is balanced.

2 H2O2(aq) ----> 2 H2O(l) + O2(g) in the presence of I-(aq) is proposed to be: Step 1 (slow): H2O2 + I- -----> H2O + OI- S

Answer:

Molecularity of the rate determining step = 2

Explanation:

Step 1 (slow): H₂O₂ + I⁻ -----> H₂O + OI⁻

Step 2 (fast): H₂O₂ + OI⁻ -----> H₂O + O₂ + I⁻

The rate determining step in a reaction mechanism is also considered as slowest step.

Slowest step is also considered its highest activation energy in energy profile diagram.

In this case intermediate (IO⁻) is formed.

Step 1 considered as a slowest step.

So, Rate = K [H₂O₂][I⁻]

Molecularity = 2
