Question

For the reaction:
Cr(H2O)6 3+(aq) + SCN–(aq) → Cr(H2O)5SCN 2+(aq) + H2O(l)
The following data were collected:

What is the rate law for the reaction?

A.

Rate = (9.1 × 10–9 M–1 hr–1)[Cr(H2O)6 3+][SCN–]

B.

Rate = (7.2 × 10–3 M–1 hr-1)[Cr(H2O)6 3+][SCN–]

✓ Correct
C.

Rate = (2.9 × 10–4 hr–1)[Cr(H2O)6 3+]

D.

Rate = (3.9 × 10–4 hr-1)[Cr(H2O)6 3+]
