Question

Processes are always spontaneous when (H and S refer to the system). When a voltaic cells reaches equilibrium What is the pH of a 0.010 M acetic acid solution? (K_a for acetic acid is 1.76 times 10^-5) 6.74 3.38 2.74 4.74 2.00 consider the equilibrium, Cl_2(g) + 2 NO(g) 2 NOCl(g). When 2.000 M NOCl is placed in a tank at 500.0 K and allowed to come to equilibrium the equilibrium concentration of Cl_2 is 0.979 M Calculate K_c 15.2 4,70 times 10^-4 0.938 45.6 What is the pH of a solution in which [HA] = [A^-]?

Explanation / Answer

19

if G <0, it is always spontanous

then

G= H - TS

if H is negative, and S positive, then it is always negaitve or G <0, this is always spotanous
