The rate of a chemical reaction is NOT affected by which of the following: A. temperature
B. particle size (surface area)
C. concentration
D. All of these affect reaction rates

What is the maximum number of electrons that an atomic orbital can contain?

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.
