You are heating a solution in the laboratory. as the solution heats up, it begins to bubble. after turning off the heat, you notice that the remaining liquid remains colorless, but you smell a sharp odor. why might you think a chemical reaction has occured?

At a certain temperature the rate of this reaction is first order in hi with a rate constant of : 0.0632s2hig=h2g+i2g suppose a vessel contains hi at a concentration of 1.28m . calculate how long it takes for the concentration of hi to decrease to 17.0% of its initial value. you may assume no other reaction is important. round your answer to 2 significant digits.
