The decomposition of XYXY is second orderin XYXY and has a rate constant of7.16×10^?3 M?1?s?1M?1?s?1 at a certaintemperature.

a) What is the half-life for this reaction at an initialconcentration of 0.100 MM?
b)

How long will it take for the concentration of XYXY todecrease to 12.5%% of its initial concentration when theinitial concentration is 0.100 MM?
c) How long will it take for the concentrationof XYXY to decrease to 12.5% of its initial concentrationwhen the initial concentration is 0.200 MM?
d) If the initial concentration of XYXY is0.140 MM, how long will it take for the concentration todecrease to 6.00×10^?2 MM?
e)

If the initial concentration of XYXY is 0.050 MM,what is the concentration of XYXY after45.0 ss?
f)

If the initial concentration of XYXY is 0.050 MM,what is the concentration of XYXY after 600 ss?
