## Spontaneouty for Diatomic molecules

Volume: $\Delta S = nR\ln \frac{V_{2}}{V_{1}}$
Temperature: $\Delta S = nC\ln \frac{T_{2}}{T_{1}}$

### Spontaneouty for Diatomic molecules

Why are diatomic molecules only spontaneous at high temperatures?

### Re: Spontaneouty for Diatomic molecules

I think it is because the element in the diatomic molecules need to be broken apart first by a high temperature in order to react spontaneously with other elements. For example, N2 would need to be broken apart as separate N elements in order for a spontaneous reaction to occur with another element. The bond holding N2 together is too strong to be broken making N2 unreactive, but N is able to react with other elements.
