1. Express the rate of reaction (in differential form) with respect to each species in the following reactions (reactants and products): (3 points)
a. N2 + 3 H2 → 2 NH3
Rate =
b. C3H8 + 5 O2 → 3 CO2 + 4 H2O
Rate = c.
3 Ca(NO3)2 + 2 Li3PO4 → 6 LiNO3 + Ca3(PO4)2
Rate =
a. N2 + 3 H2 → 2 NH3
dN2/dt = 1/3*d(H2)/dt
-dN2/dt = 1/2*d(NH3)/dt
-d(H2)/dt = 2/3*d(NH3)/dt
b. C3H8 + 5 O2 → 3 CO2 + 4 H2O
d(C3H8)/dT = 1/5*d(O2)/dT
-d(C3H8)/dT = 1/3*d(CO2)/dT
-d(C3H8)/dT = 1/4*d(H2O)/dT
c)
3 Ca(NO3)2 + 2 Li3PO4 → 6 LiNO3 + Ca3(PO4)2
d(Ca(NO3)2)/dT = 3/2* d(Li3PO4)/dt
-d(Ca(NO3)2)/dT = 3/6* d(LiNO3 )/dt
-d(Ca(NO3)2)/dT = 3*d(Ca3(PO4)2)/dt
