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 0.25 h, while that of Y is 150. min. Suppose an atmospheric scientist studying these decompositions fills a transparent 5.0 L flask with X and Y and exposes the flask to UV light. Initially, the partial pressure of X is 25.0% 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. ○ yes O no min
