5.4A For the catalytic cycle Cl03 CIO O k 2.9 x 10 exp(260T) CIOO CI O k 3.0 x 1011 exp(70T) determine the ratio of CIO03 at which the rate of ozone destruction from this cycle equals that from the Chapman cycle at 20 km, where T220 K. If the O3 mixing ratio is 4ppm, what concentration of CIO does this correspond to
5.4. For the catalytic cycle C1 +03 - CIO+ O2 k? = 2.9 x 10-11 exp(-260/T) CIO+ O 2 CI+ O2 k2 = 3.0 x 10-11 exp(70/T) determi

A 10 L container is filled with 0.11 mol of H2(g) and heated to 3200 K causing some of the H2(g) to decompose into H(g). The pressure is found to be 3.2 atm . Find the partial pressure of the H(g) that forms from H2 at this temperature.

If you have 0.20 mol of silver permanganate (AgMNO4), which has a solubility of about 16.7 g/L, what is the minimum amount of water youll need to get it all into solution? At what temperature? Report your answer to the nearest whole mL.

Why would benzaldehyde react differently than other aldehydes?

Show the chemical reaction that takes place when Benedicts reagent (Cu) reacts with glucose (use open chain Fisher projection). Do you expect fructose to give a positive reaction with Barfoeds reagent Explain why or why not. Indicate which of the test carbohydrates (glucose, fructose, xylose, lactose, sucrose, starch) would give furfural when
Show the chemical reaction that takes place when B

An INSULATED system contains two compartments 1 and 2, containing N 1 and N 2 molecules of an ideal gas, respectively. The compartments are linked by a movable, insulating, impermeable wall. Thus the compartments can exchange volume, while the total volume V T = V 1 + V 2 is conserved. (a) Assume that each box can be subdivided into very small
