Need experts solution only, Don't use AI 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 is1.25 h, while that of Y is 15. min. Suppose an atmospheric scientist studying these decompositions fills a transparent 20.0 L flask with X and Y and exposesthe flask to UV light. Initially, the partial pressure of X is 4.0 times greater than the partial pressure of Y.As both gases decompose, will the partial pressure of X ever fallbelow the partial pressure of Y?If you said yes, calculate the time it takes the partial pressure of Xto fall below the partial pressure of Y. Round your answer to 2significant digits.yes• поXminG

a.Yes, after a certain amount of time, the concentrations of gas X will reach a level whereby the…
