Give the units of the rate constants in terms of the power x in. M^x time-1 for reactions with the following overall orders. a) first order. b) 5/2 order. I know the units for the first order are. Mol L^-1 / s = k(mol L-1). K = s^-1. but in terms of what the question is asking, the x , I don't understand what they want...
The Arrhenius equation provides a relationship between the rate constant k and temperature T. The Arrhenius equation is: k=zpeâEaRT. where, k is the rate constant, z is the collision factor, p is the steric factor, Ea is the activation energy, R=8.3245Jmol.K is the ideal gas constant. and T is the temperature. The Arrhenius equation could also be written as: k=AeâEaRT, where, A=zp is the Arrhenius factor. Taking the natural logarithm of both parties, we get: lnk=âEaR(1T)+lnA.
