(a) Of the three substances in the equation, lets choose O2 as the reference because its coefficient is 1. For every molecule of O2 that disappears, two molecules of H2 disappear. Thus, the rate of [O2] decrease is one-half the rate of [H2] decrease. By similar reasoning, the rate of [O2] decrease is one- half the rate of [H2O] increase.b) Because [O2] is decreasing, the […]
