Verify Stokes' Theorem for the given vector field and surface, oriented with an upward-pointing normal:

$\mathbf{F} = \left< e^{y-z}, 0,0\right>,\quad$ the square with vertices $(3,0,6)$, $(3,3,6)$, $(0,3,6)$, and $(0,0,6)$.

$\int_{\mathcal{C}} \mathbf{F} \cdot d\mathbf{s}=$

$\iint_{\mathcal{S}} \text{curl} (\mathbf{F})\cdot \,d\mathbf{S} =$
