A rigid vessel contains a mixture of \(0.10 \text{ mol}\) of \(\text{Ne(g)}\) and \(0.30 \text{ mol}\) of \(\text{Ar(g)}\) at an initial temperature of \(300 \text{ K}\). The total pressure inside the vessel at \(300 \text{ K}\) is \(8.0 \text{ atm}\). If the vessel is heated to \(450 \text{ K}\), what is the partial pressure of \(\text{Ne(g)}\) at \(450 \text{ K}\)?
