Half-life and k are inversely proportional

WebInversely Proportional: when one value decreases at the same rate that the other increases. Example: speed and travel time Speed and travel time are Inversely Proportional because the faster we go the shorter the time. WebSolution Verified by Toppr Correct option is C) k=Ae − RT Ea Rate constant (k) is related to temperature as the above relation. As temperature increases, rate constant also increases and half life decreases. ( half-life is inversely proportional to rate constant). Was this answer helpful? 0 0 Similar questions

Just divide both sides … Web8 years ago. In earlier videos we see the rate law for a first-order reaction R=k [A], where [A] is the concentration of the reactant. If we were to increase or decrease this value, we see that R (the rate of the reaction) would increase or decrease as well. When dealing with half-life, however, we are working with k (the rate constant).
