Received July 1 2 , 1971 The kinetics of the acid-catalyzed aquation of cis-bis(malonato)diaquochromate(III) and the isomerization of tvans-bis(malonato)diaquochromate(III)are reported. The rate laws (rateconstants at 25" and I = 1.0 Mfollow in parentheses) are -d[cis-Cr(C3H204)2(H~O)~-]/dt = k[cis-Cr(C&I20
