You can try restarting Steam to see if SpaceChem shows up.
My own previous experience is that it can take some time for the games to show up in your Steam list. The fastest way is usually to restart Steam. Otherwise be patient, it will show up. The previous bundle had 3 games added post and they all showed up fairly quickly in the Steam list once activated.
