Calculate the value of ΔG∘rxnΔGrxn∘ for the following reaction at 296 K. Ka = 2.9 × 10–8 and assume Ka does not change significa

oee [108]

Answer:

$\Delta G_{rxn}=42.7\frac{kJ}{mol}$

Explanation:

In this case, for the dissociation of hypochlorous acid, we know that the acid dissociation constant (Ka) is 2.9x10⁻⁸, which is related with the Gibbs free energy as shown below:

$\Delta G_{rxn}=-RTln(K)$

But in this case K is just Ka, therefore, at 296 K, it turns out:

$\Delta G_{rxn}=-8.314\frac{J}{mol*K}*296K*ln(2.9x10^{-8})\\\\\Delta G_{rxn}=42.7\frac{kJ}{mol}$

Such result, means that the reaction is nonspontaneous at the given temperature, it means it is not favorable (not easily occurring).

Best regards.

How can an electron have no net electrical charge?

solong [7]

Well not to sure if that statements true... but in hydrogen for example both its proton and electron have an electric charge but one has a + charge (proton) and the other a - charge (electron) so they end up cancelling so there is no net electrical charge

hope that helps
