Molecular iodine, i2 (g), dissociates into iodine atoms at 545k with a first order rate constant of 0.344 1/s. if you start with 0.054 m i2 at this temperature how much will remain after 5.16 s?

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

The second and last option are the answers
