(a) ΔrG° for the following reaction at 398 K is 2.6 kJ
mol−1:
H2(g) + I2(g) → 2 HI(g)
If a gas mixture containing: 2.00 bar of H2, 2.00 bar of iodine
vapour, and 0.500 bar of hydrogen iodide, is sealed in a container
at 398 K, is the reaction at equilibrium? [4]
(b) Sketch a graph to show how the conductivity of a solution
varies with concentration depending on whether the solute is a
strong or weak electrolyte....
