<span style="font-family: Roboto; font-size: 11pt;">In this presentation, the adsorption reactions of CO</span><sub style="font-family: Roboto; font-size: 11pt;">2</sub><span style="font-family: Roboto; font-size: 11pt;"> on SrO surfaces and its hydrated counterparts are examined. The predicted energies of CO</span><sub style="font-family: Roboto; font-size: 11pt;">2</sub><span style="font-family: Roboto; font-size: 11pt;"> adsorption on follows the order of increasing H</span><sub style="font-family: Roboto; font-size: 11pt;">2</sub><span style="font-family: Roboto; font-size: 11pt;">O content. The carbonation on the monohydrate surface is barrierless, whereas the CO</span><sub style="font-family: Roboto; font-size: 11pt;">2</sub><span style="font-family: Roboto; font-size: 11pt;"> reaction on the Sr(OH)</span><sub style="font-family: Roboto; font-size: 11pt;">2</sub><span style="font-family: Roboto; font-size: 11pt;"> and the octahydrate surfaces follows pathways with finite activation barriers. The thermodynamics of bulk reaction is also addressed.</span>
