29: Which is the correct statement from the following statements on the Arrhenius model of the rate constant k = Ae-E/RT? (A) A is always dimensionless, (B) For two reactions 1 and 2, if A₁ = A₂ and E₁ > E₂, then k₁ (T) > k₂ (T) (C) For a given reaction, the % change of k with respect to temperature is higher at lower temperatures. (D) The % change of k with respect to temperature is higher for higher A.
