Instrumental Analysis question help, thank you!

In experiment 1, a cyclic voltammogram at a mercury electrode was obtained from a 0.167 mM solution of Pb2+ at a scan rate of 2.5 V/s. In experiment 2, a second CV is to be obtained from a 4.38 mM solution of Cd2+ using the same mercury electrode.

What must the scan rate be in experiment 2 to record the same peak current in both experiments if the diffusion coefficients of Cd2+ and Pb2+ are 0.72 x 10-5 cm2s-1 and 0.98 cm2s-1 respectively? Assume that the reductions of both cations are reversible at a mercury electrode.
