Part 1 Element D reacts with F2 to form gaseous DF4. A series of experimental trials to determine the rate law expression for the reaction. 1. A student claims that the reaction is second order with respect to F2 (g). Do you agree or disagree? Justify your answer. 2. If Element D is in group 16, then the molecular geometry of DF4 (g) is see-saw. Do you agree or disagree with this claim? Justify your answer in terms of VSEPR theory.
Part 1
Element D reacts with F2 to form gaseous DF4. A series of experimental trials to determine the rate law expression for the reaction.
1. A student claims that the reaction is second order with respect to F2 (g). Do you agree or disagree? Justify your answer.
2. If Element D is in group 16, then the molecular geometry of DF4 (g) is see-saw. Do you agree or disagree with this claim? Justify your answer in terms of VSEPR theory.
Part 2
The particle model below shows the moles of D (g) and F2 (g) present after a separate reaction occurs. Assume each particle represents one mole. Note, the “Before Reaction” box is intentionally left blank.
1. What is the partial pressure of D (g) if the final total pressure is 12 atm?
2. Assuming that only D and F2 are present before the reaction, how many moles of D and F2 that initially were present?
