If δh = -70.0 kj and δs = -0.400 kj/k , the reaction is spontaneous below a certain temperature. calculate that temperature.
Trava [24]
According to this formula, when:

ΔG = ΔH  - T*ΔS

when the reaction is thermodynamically spontaneous ΔG < 0 

∴ ΔH - T* ΔS = 0 

∴T*ΔS = ΔH

∴ T = ΔH / ΔS

when we have:

ΔH = -70KJ

and ΔS = -0.4 KJ/K

So by substitution:

T =  -70KJ /- 0.4

  =  175 K 

∴the certain temperature below which the reaction will be thermodynamically spontaneous is 175 K

Answer:

The answer is "5.18 ".

Explanation:

It's a question of chemistry. Therefore, the following solution is provided:

We will first determine the solution's pOH. The following can possible:

The concentration of Hydroxide ion [OH^{-}] = 1.5\times 10^{-9}\ M

pOH =?\\\\pOH = -\log [OH^{-}]\\\\pOH = -\log 1.5\times 10^{-9}\\\\pOH = 8.82\\\\

Furthermore, the pH of the solution shall be established. It was provided as follows:

pOH = 8.82\\\\pH =?\\\\pH + pOH = 14\\\\pH + 8.82 = 14\\\\

When collecting all the like terms:

pH = 14 -8.82\\\\pH = 5.18

Therefore, the solution of pH is 5.18.
