I have some quick questions that I need some help with: 1. Why would a simple chemical reaction such as NO9g) + 1/2O2(g) -----------> NO2(g) most likley be most rapid at the start? 2. In what ways can the rate of dissolving a lump of sugar be increased? (at least 3) 3. Finally, what effect would there be on the rate of constant of, forward reaction, and reverse reaction if there was an increase in temperature?
