Kinetic data and their interpretation - Reaction kinetics: the relation between rate and concentration

3 important questions on Kinetic data and their interpretation - Reaction kinetics: the relation between rate and concentration

What is the equation of the halflife time  for first order reactions?

t0.5 = ln(2)/k1

When the change in concentration of B equals its formation from A minus its reaction to form A, what can we write?

dx/dt = k1 [A]0 - (k1+k-1)x

What needs to be assumed for preequilibria and what is the rate equation?

The assuption that needs to be made is that the reaction is in steady state

v = k2[AB] = (k1k2[A][B])/(k-1 + k2)

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
Remember faster, study better. Scientifically proven.
