Write Lewis structures for CO32-, HCO3-, and H2CO3. When acid is added to an aqueous solution containing carbonate or bicarbonate ions, carbon dioxide gas is formed. We generally say that carbonic acid (H2CO3) is unstable. Use bond energies to estimate ΔE for the reaction (in the gas phase) 

H2CO3 → CO2 + H2

The reaction

I - (aq) + OCl - (aq) → IO - (aq) + Cl - (aq)

was studied, and the following data were obtained:

c. Calculate the initial rate for an experiment where both I  - and OCl - are initially present at 0.15 mol/L.

Sulfuryl chloride (SO2Cl2) decomposes to sulfur dioxide (SO2) and chlorine (Cl2) by reaction in the gas phase. The following pressure data were obtained when a sample containing 5.00 x 10-2 mol sulfuryl chloride was heated to 600. K in a 5.00 x 10 -1-L container.

Defining the rate as - Δ [SO2Cl2] / Δt,
a. determine the value of the rate constant for the decomposition of sulfuryl chloride at 600. K.
