Molecular iodine, I2(g), dissociates into iodine atoms at 625 K with a first-order rate constant of 0.271 s-1. f you start with 0.051 M I2 at this temperature, how much will remain after 5.05 s assuming that the iodine atoms do not recombine to form

The rate constant for the reaction is 0.450 M−1⋅s−1 at 200 ∘C.   A⟶products If the initial concentration of A is 0.00610 M, what will be the concentration after 405 s?

DDT is a pesticide that has been useful in controlling mosquito-born diseases, however it degrades slowly. In one experiment it took 53.2 years for a sample of DDT to degrade to 1% of it initial value with first order reaction kinetics. What is the first order rate constant for the dissappearence of DDT?

Gaseous SO2Cl2 undergoes the following decomposition:   SO2Cl2 (g) --> SO2(g) +Cl2(g) The above reaction has a second-order kinetic dependence on the SO2Cl2 concentration with a rate constant of (0.00400 M-1* s-1). If one starts with 0.0641 molar SO2Cl2 at time zero, what is the calculated molar concentration of SO2Cl2 remaining after 40.23 minutes of decomposition of the initial  SO2Cl2

Radioactive decay of unstable atomic nuclei is at first order process. The half-life for the radioactive decay of 14C is 5730 years. An archeological sample contained wood that had 87% of the 14C found in living trees. How old is the archaeological sample (in years)?

Consider a hypothetical reaction: A → 3B + C The reaction is 2nd order and k = 0.0220 M-¹s-¹. Starting with initial [A] = 0.195 M and no other substance in the container, calculate [B] after 24.0 seconds of reaction time. Hint: Solve for final concentration of A and use stoichiometry.
