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 1.75 h, while that of y is 120. 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 4.0 times greater than the partial pressure of y. 1. as both gases decompose, will the partial pressure of x ever all yes below the partial pressure of y? a. yes. b. no.2. if you said yes, calculate the time it takes the partial pressure of x to fall below the partlal pressure of y. round your answer to 2 significant digits. =.
