Chemical Kinetics (5/8)

end of the line is below the start= products are favored and spontaneous (-G)

K=Ae^(-E_a/RT)

Biological catalysts reduce the activation energy of a reaction • stabilizes • weakens bonds • increases collisions • donates electron density • DOES NOT change enthalpy or ∆G (cannot make a reaction spontaneous)

Heterogeneous= different phase than reactants Homogeneous= Same phase as reactants

The reactants are lower in energy than the products, the transition state is higher in energy than the products, the reaction has a positive ∆H

Math expression for the relationship between [r] and rate of reaction

rate= K[A]^x[B]^y

1/(M^2*s)

1/(M*s)

1/s

M/s

The difference in energy between the reactants and the transition state
