rates of reaction

if given 50cm^3 of 1.0 mol dm^-3

which one of the following would give a faster rate of reaction

25 cm^3 of 2.0 mol dm^-3 or 100cm^3 of 0.5 mol dm^-3

thanks in advance :smile:
100cm^3

why?
Both have 50*10^-2 mol of something but the 100c^3 of solution has a larger volume so there is more total available surface area and volume where the reaction can take place.

Thats my guess. Check with someone else.
