rest of handouts 1-3 Flashcards
1
Q
why not separate variables in unimolecular reversable reaction
A
extra variable
cA, cB and t
2
Q
integrated rate law for reversable unimolecular reaction
A
deltacA(t) = deltac0A exp (-(ka + kb)t) with delts cA(t) = cA(t) - cAeq
3
Q
shape of integrated reversible graph
A
decays exponentially to equilibrium line
4
Q
equation at relaxation time
A
tau R = 1/ ka +kb
5
Q
differential rate equation for reversable unimolecular equation
A
-d[A]/dt = ka[A] -kb[B]
6
Q
how to find thermodynamic equilibrium constant
A
[B]eq / [A]eq
7
Q
differential equation for a zeroth order reaction
A
dcA (t)/dt = dcB)/dt=k
8
Q
integrated time law zeroth order reaction
A
cA(t) = c0A - kt
9
