At another temperature, the rate constant for the reaction inexercise 3 is 0.15 s−1 . If the initial concentration of PCl5 is2.2 M, what is its concentration after 25 seconds? (Answer key:0.052 M)
***This was questions 3: For the first-order reactionrepresented by the equation PCl5(g) → PCl3(g) + Cl2(g), thehalf-life is 24 seconds at a certain temperature. What is the valueof the rate constant (including units)? If we start with 0.100 MPCl5, how long will it be until [Cl2] = 0.020 M? (Hint: What willbe the concentration of PCl5 at that point?)
