What are the signs of $\mathrm{\Delta }H$ and $\mathrm{\Delta }S$ for this reaction?

$2\mathrm{C}\left(s\right)+{\mathrm{O}}_2\left(g\right)⟶2\mathrm{CO}\left(g\right)$

Given reaction is,

$2\mathrm{C}\left(s\right)+{\mathrm{O}}_2\left(g\right)⟶2\mathrm{CO}\left(g\right)$

Entropy will be decreased and its sign will be negative as the number of moles is decreasing.  Here, the change in enthalpy is also negative for this.
