The reaction 2HI --> H2 + I2 is second
order in [HI] and second order overall. The rate constant of the
reaction at 700 degrees celsius is 1.57 x 10-5
M-1 s-1. Suppose you have a sample in which
the concentration of [HI] is 0.75 M. What was the concentration of
HI 8 hours earlier?

For a reaction that is either zero, first, or second order,
which reaction order would leave the most reactant remaining after
the reaction has occurred for an hour? Assume k does not
change.
1.)For a second-order reaction, the initial reactant concentration is 0.62 M. After 36.3 min, the concentration...
1.)For a second-order reaction, the initial reactant
concentration is 0.62 M. After 36.3 min, the concentration is 0.22
M. What is k in M-1min-1?
2.) For a second order reaction, the initial reactant
concentration, [A]o, is 0.84 M. After 12.6 s, the concentration is
0.62 M. What is [A] after 81 s? Hint given in feedback

A student is studying a reaction between reactants A and B. the
reaction is second order with respect to A, but zero order with
respect to B. Explain in 5-6 sentences what this means.
If the Concetration of A is tripled what will the effect be on the
reaction rate?
If the concentration of B is increased 10 times, what will the
effect be on the reaction rate?

The reaction A(aq) → 2 B(aq) is a second order reaction with
respect to A(aq). Its activation energy is 41.3 kJ/mol. When the
concentration of A(aq) is 0.100 M and the temperature is
25.0oC, the rate of reaction is 0.333 M/s. What is the
rate of reaction when we increase the concentration of A(aq) to
0.272 M and we raise the temperature to 54.9 oC?
