A TIO2 photocatalyst was used to destroy pollutant compounds in a sample of water. The catalyst was irradiated with 250 nm radiation from a 300 W source for 90 minutes. 40% of the light was reflected off the catalyst and the rest was absorbed. After irradiation it was found that 0.02 moles of the pollutant compound had been decomposed. Calculate the quantum yield of the photo-decomposition process.

Two gases X and Y are found in the atmosphere in only trace amounts because they decompose quickly. When exposed to ultraviolet light the half-life of X is 15. min, while that of Y is 2.50 h. Suppose an atmospheric scientist studying these decompositions fills a transparent 10.0 L flask with X and Y and exposes the flask to UV light. Initially, the partial pressure of X is 5.0 times greater than the partial pressure of Y. As both gases decompose, will the partial pressure of X ever fall below the partial pressure of Y? If you said yes, calculate the time it takes the partial pressure of X to fall below the partial pressure of Y. Round your answer to 2 significant digits. O yes O no min 0 0 14
Cryosurgical procedures involve lowering the patient’s body temperature prior to the surgery. If the activation energy, Ea, for the beating of the heart muscle can be estimated to be about 30 kJ and the normal pulse rate at 37°C is 75 beats/minute, estimate the pulse rate if the body temperature is lowered to 22°C.
A chemical is sprayed onto a lawn at a rate of 0.90 kg active ingredient per hectare. The chemical has a half-life of 30 days at 20C. A storm event occurs 15 days after application and causes 3.5% of the material present in the 25 hectare field to be lost (total losses). If average temperatures during the 15-day period were 17C, how much material (mass) was lost during the storm?
