PSC 480/740 Problem Set 2 Questions Chapter 2, Levenspiel 1.
1 ANSWER KEY
If the reaction is not elementary, one cannot know the order. If the reaction is elementary, the order is 2nd in either direction. −[ A ] = k1[ A][B] dt
d [A ] = k −1[ R ]2 dt
2.
1 − d [ NO 2 ] d [O 2 ] d [ N 2 O5 ] = −2 = 2 dt dt dt
3.
The same. ( rA =

a)
atm-1 hr-1
b)
One mole of an ideal gas at 400°K occupies 32.82 L ⋅ atm . PV L ⋅ atm L ⋅ atm × 400 K = 32.82 = RT = 0.082053 n K ⋅ mol mol
d [A ] , regardless of how the stoichiometric equation is written.) dt

8.
If 1 >> k2[N2O], then the reaction is second order in N2O, and second order overall. If 1
