WebThe reaction rate increases in the direction where there are fewer moles of gas and decreases in the reverse direction. For condensed-phase reactions, the pressure dependence is weak. The order of the reaction controls how the reactant concentration (or pressure) affects the reaction rate. WebFeb 12, 2024 · Differential rate laws are generally used to describe what is occurring on a molecular level during a reaction, whereas integrated rate laws are used for determining the reaction order and the value of the rate constant from experimental measurements. The differential equation describing first-order kinetics is given below: WebSep 24, 2024 · collision frequency, thus causing the reaction to proceed at a faster rate. The proximity effect effectively increases the local concentration of substrate (recall that rate is proportional to substrate concentration).

WebThe reaction rate changes in direct proportion to the change in [O 3 ]. When [O 3] doubles from trial 1 to 2, the rate doubles; when [O 3] triples from trial 1 to 3, the rate increases also triples. Thus, the rate is directly proportional to [O 3 ], and n is equal to 1.The rate law is thus: rate = k[NO]1[O3]1 = k[NO][O3] Step 3.
