Hydrogen iodide decomposes slowly to H2 and I2 at 600 K. The reaction is second order in HI and the rate constant is 9.7×10−6M−1s−1. Part A What is the half-life (in days) of this reaction when the initial HI concentration is 0.120 M ? Express your answer using two significant figures. t1/2 t 1 / 2 = days Previous AnswersRequest Answer Incorrect; Try Again; 4 attempts remaining Part B How many days does it take for the concentration of HI to drop from 0.220 M to 5.50×10−2 M ? Express your answer using two significant figures. t t = nothing days Request Answer Provide Feedback
