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 X 4 7² $

Hydrogen peroxide and the iodide ion react in acidic solution as follows: H2O2(aq)+3I(aq)+2H+(aq)I3(aq)+2H2O(l) The kinetics of this reaction were studied by following the decay of the concentration of H2O2 and constructing plots of ln[H2O2] versus time. All the plots were linear and all solutions had [H2O2]0 = 8.0 104 mol/L. The slopes of these straight lines depended on the initial concentrations of I and H+.
