The enantiospecific surface chemistry of chiral adsorbates on chiral metal surfaces is the quintessential form of structure sensitive surface chemistry.  It is dictated solely by the disymmetric relationships between surface and adsorbate structures.  As is true for all problems of structure sensitive surface chemistry, comprehensive study and understanding requires measurements that span surface orientations in a continuous fashion.  We have developed the use of spherically shaped single crystal surfaces to measure surface reaction rate constants across continuous regions of surface orientation space.  The decomposition kinetics of tartaric acid on Cu(<i>hkl</i>) surfaces with normal vectors lying within 12<sup>o</sup> of [110], [100] and [111]  directions exhibit high enantiospecificity.  Within the Cu(110) region of surface orientation space we have identified a surface orientation that maximizes enantiospecificity
