Step 1 : A +B <==> C + D
( k1 in fwd direction, k2 in rev direction)
Step 2: A + C ==> B+D
(k3 in fwd direction)
Match the expressions to complete the equations, making use of the Steady State Approximation.
A) 2(k1)(k3)[A]^2[B] / (k2)[D]
B) (k1)[A][B] / (k3)[A]
C) 2(k1)(k3)[A]^2[B] / (k2)[D] +(k3)[A]
D) (k1)[A][B] / (k2)[D] + (k3)[A]
E) 2(k1)[A][B]
F) (k1)[A][B] - (k2)[C][D] - (k3)[A][C]
G) (k1)[A][B] / (k2)(k3)[A][D]
H) None of the above
match with!! _______
1. -d[A]/dt (in all instances)
2. d[D]/dt (when k3 >> k1 =k2)
3. d[D]/dt (when k3 <<k1=k2)
4. d[C]/dt
5. =[C]
I think 4 is F and 5 is D.
The rate I got in the end was: k1k3[A]^2[B]/k2[D]+k3[A]
but I'm pretty sure this isn't right..
