Molecular iodine, I2(g), dissociates into iodine atoms at 625 K with a first-order rate constant of 0.271 s-1.
(a) What is the half-life for this reaction?
_______ s
(b) If you start with 0.051 M I2 at this temperature, how much will remain after 5.30 s assuming that the iodine atoms do not recombine to form I2?
_______ M
half-life = 0.693 / 0.271 = 2.5571 Sec
ln A = -kt + ln Ao
ln A = - 0.271 x 5.3 + ln 0.051
ln A = 1.21 x 10-2 M

Iodine atoms will combine to form I2 in liquid hexane solvent with a rate constant of 1.5×1010L/mol⋅s. The reaction is second order in I . Since the reaction occurs so quickly, the only way to study the reaction is to create iodine atoms almost instantaneously, usually by photochemical decomposition of I2. Suppose a flash of light creates an initial [I] concentration of 1.00×10−2M . Question: How long will it take for 94% of the newly created iodine atoms to recombine...
The dissociation of molecular iodine into iodine atoms is represented as I2(g) ⇌ 2I(g) At 1000 K, the equilibrium constant Kc for the reaction is 3.80 × 10−5.

A compound dissociates into its elements at 625 K in a first order process with a rate constant of 0.063s-1. If you start with a 0.26 M concentration of the compound at this temperature, what will the concentration be after 2.285s? (Assume that the compound is not reformed once it dissociates.) I am not sure how to solve it :(((( Please help me.
