... This equation as written is unbalanced. On the left side of the arrow (reactant side), there are 2 atoms of oxygen. On the right side of the arrow (product side), there is only one atom of oxygen. A quick-and-easy attempt to balance the two sides may be to add a subscript to the H2O formula, so it a ...

... Why do chemists want to know the rate of a reaction? If you are making a product, it is important to know how long the reaction takes to complete, before the product is produced. Rate is a measure of a change that happens over a single unit time. That unit time is most often a second, a minute, or a ...

... Step 2 is rate determining step and this will determine the rate of the reaction. The subsequent step can be ignored in working out the rate. Step 2 involves the decomposition of N2O4 and depends only on its concentration: rate = k2[N2O4(g)] As this involves the concentration of a reaction intermedi ...
