18. Solving a chemistry problem

6. A dilute aqueous solution of MeCl2 is saturated with hydrogen gas at 298 K and 1 atm. Define for reaction
H2 (g) MeCl2 \u003d Me 2H aq 2Cl-aq
1) thermal effect at Р = const; 2) change in entropy; 3) standard change in Gibbs energy; 4) logarithm of the equilibrium constant; 5) establish whether the reaction will proceed spontaneously under the indicated conditions:

Option 6
MeCl2 CdCl2
