The exponent, m, (rounded to the nearest whole number) in the rate equation:

Rate = k[H2O2]^m[I-]^n

I know I could put exp 1 over exp 2 and solve, but I don't have a concentration for I, just KI.

Question

The exponent, m, (rounded to the nearest whole number) in the rate equation:

Rate = k[H2O2]^m[I-]^n

I know I could put exp 1 over exp 2 and solve, but I don't have a concentration for I, just KI.

Each trial has different amounts of KI, H2O2 and water, but even if i find the concentration of KI, it's not I.

jfraser · Answer

the concentration of KI and the concentration of I- will essentially be the same, because KI is a soluble ionic compound, and will dissociate in water

jfraser · Answer

the potassium ion is a spectator here
