(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
What would you multiply "grams of iodine" by to get the units "atoms of iodine" ? What would you multiply "grams of sulfur" by to get the units "atoms of sulfur" ? What would you multiply "atoms of rubidium" by to get the units "grams of rubidium" ?
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...
Theory: Tin (II) Iodide is not a thermodynamically favored substance. What this means is that if you mix Tin and Iodine, nothing will happen. So Tin(II) chloride + Zinc(II) iodide is used instead to synthesize Tin(II) iodide. Can I have an explanation of why this is? I am looking at the reduction potentials and it seems the reaction is spontaneous however, so I am confused.
