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 2.00 h, while that of Y is 45. min. 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 75.0 % 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. O yes O no min 0.2 X

Transcribed Image Text: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
2.00 h, while that of Y is 45. min. 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 75.0 % 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.
