Consider the following pairs of complexes [CoF(NH3)5]2+ and [Cr(OH2)6]2+[Co(NH3)5 (OH2)]3+ and [Cr(OH2)6]2+[Co(NH3)6]3+ and [Cr(OH2)6]2+[CoI(NH3)5]2+ and [Cr(OH2)6]2+The electron transfer rate will be fastest in the pair
- Hemoglobin is an oxygen carrying protein. The correct statement about oxy-hemoglobin is that
- If a mixture of NaCl, conc. H2SO4 and K2Cr2O7 is heated in a dry test tube, a red vapour (P) is formed. This vapour (P) dissolves in aqueous NaOH to form a yellow solution, which upon treatment with AgNO3 forms a red solid (Q). P and Q are, respectively
