Reaction Kinetics

3 concentration of N 2, H 2, or NH 3Say we monitor N 2, and obtain a rate of - d N 2 dt = x mol dm-3 s-1 Since for every mole of N 2 that reacts, we lose three moles of H 2, if we had monitored H 2 instead of N 2 we would have obtained a rate - d H 2 dt = 3x mol dm-3 s-1Similarly, monitoring the concentration of NH 3 would yield a rate of 2x mol dm-3 s-1Clearly, the same ,...
