Answer:
[tex]C+O_2\ \overrightarrow{Pd} \ CO_2[/tex]
Explanation:
Hello!
In this case, since the catalytic reactions involve the presence of a catalyst that decrease the activation energy of the undergoing chemical reaction, when we need to include it in the chemical equation, we usually put on or underneath the reaction arrow, just as shown below:
[tex]C+O_2\ \overrightarrow{Pd} \ CO_2[/tex]
Best regards!
