At a certain temperature, when I2(s) is dissolved in CCl4(l), the Henry’s coefficient for iodine, kx(I2), was found to be 54.6 kPa. If the partial pressure of I2 in the gas phase is P(I2) = 16.72 kPa, and the molar fraction of iodine in the CCl4 solution in equilibrium with it is x(I2) = 0.50, then the activity of iodine in this solution, a(I2), = ( ), and the activity coefficient of iodine, γ(I2), = ( ).
