When heated, iodine vapor dissociates according to this equation: I2 (g)⇌2I (g)I2 (g)⇌2I (g) At 1274 K, a sample exhibits a partial pressure of I2 of 0.1122 atm and a partial pressure due to I atoms of 0.1378 atm. Determine the value of the equilibrium constant, KP, for the decomposition at 1274 K. 57.
WebThe melting point of iodine is 113.7°C. Once heated to this temperature, solid iodine will begin producing a purple vapor. To create liquid iodine, you'd need to keep the material at just below 113°C and then introduce the correct atmospheric pressure to keep the element from vaporizing. Thank Writer Blurt Anonymous answered Iodine is a solid. Web2-Iodothiophene is obtained in good yield by iodination with iodine and iodic acid in sulfuric acid, by iodination in the presence of mercury(II) oxide (Section 3.14.2.4), or by iodination of 2-thienyllithium (Section 3.14.3.9). 3-Iodothiophene was first prepared by removal of three iodine atoms from tetraiodothiophene, but is more conveniently obtained by reaction of …
