WebApr 7, 2016 · I'm doing a high school/sixth form college investigation of the kinetics between magnesium ribbon and hydrochloric acid. I have obtained a rate order was $1.5$ with reference to $[\ce{H+}]$ and hence the rate equation is $$\mathrm{rate} = k[\ce{H+}]^{1.5}.\tag{1}$$ How does this fractional order correlate with the mechanism? WebThe units for k should be mol −2 L 2 /s so that the rate is in terms of mol/L/s. To determine the value of k once the rate law expression has been solved, simply plug in values from the first experimental trial and solve for k: 0.00300molL − 1s − 1 = k(0.10molL − 1)2(0.10molL − 1)1 k = 3.0mol − 2L2s − 1 Exercise 17.3.3
