Which reaction occurs with the greater increase in entropy? Explain your reasoning.

(a) ${\text{2H}}_{\text{2}}\text{O}(\mathcal{l})\to {\text{2H}}_{\text{2}}\left(\text{g}\right)+{\text{O}}_{\text{2}}\left(\text{g}\right)$

(b) $\text{C}\left(\text{s}\right)+{\text{O}}_{\text{2}}\left(\text{g}\right)\to {\text{CO}}_{\text{2}}\left(\text{g}\right)$
