Question

For a reaction, A(g) $ \to $ A($\ell $); $\Delta $H= $-$ 3RT.
The correct statement for the reaction is :

$\Delta $H = $\Delta $U $ \ne $ O

$\Delta $H = $\Delta $U = O

$\left| {} \right.$$\Delta $H$\left| {} \right.$ < $\left| {} \right.$$\Delta $U$\left| {} \right.$

$\left| {} \right.$$\Delta $H$\left| {} \right.$ > $\left| {} \right.$$\Delta $U$\left| {} \right.$
