10. In an experiment, a sample was 90% decomposed in 24 min. Approximately how long would this decomposition have taken if the sample had been heated 20°C higher? (Hint: Assume the rate doubles for each 10°C rise in temperature.)

11. Find which kind of catalyst is necessary to facilitate the reaction between molecular nitrogen and molecular hydrogen to make ammonia (several words description)

In an experiment, why would the concentration of a sample decrease when changing the wavelength for a spectrophotometer from 235 nm to 280 nm? This is just a general question, I would like to know why the absorbance peak would be higher at a wavelength of 235nm rather than at 280nm. Is this normal? or could it an experimetnal error?
