The step with larger activation energy is the slower step (as the fraction of collisions w/ enough energy to react will be smaller - activation energy requirement is higher) This derives from the Arrhenius equation: k = A * e^ (-Ea/RT) where A and R are constants, T = temp, and Ea = activation energy. As you can see, as Ea increases, k decreases.This equation can be used to understand how the rate of a chemical reaction depends on temperature. The Arrhenius equation is k = Ae^(-Ea/RT), where A is the frequency or pre-exponential factor and e^(-Ea/RT) represents the fraction of collisions that have enough energy to overcome the activation barrier (i.e., have energy greater than or equal to the activation energy Ea) at temperature T.Ideal gas equation example 3 | Chemistry | Khan Academy Ideal gas equation example 4 | Chemistry | Khan Academy Introduction to partial pressure | Gases and kinetic molecular theory | Chemistry | Khan Academyપ્રક્રિયા ક્રિયાવિધિ, મધ્યવર્તી, અને વેગ માર્યાદિત તબક્કાની.Извеждане на различни форми на уравнението на Арениус.
