What would you do in the laboratory to obtain data to confirm the order in the rate expression for either of the reactants?
What would you do in the laboratory to obtain data to confirm the order in the rate expression for either of the reactants? plotting ln[OH-] vs time, if a straight line results, the reaction is 1st order with respect to [OH-].

Does AP Chem have FRQS?
The 2020 free-response questions are available in the AP Classroom question bank.
Do sig figs matter AP Chemistry exam?
The exam question associated with significant figures will most likely not be labeled and the students will have no way of knowing when to use significant figures; therefore, they must round their answers to the appropriate number of significant figures for every calculation to obtain the single point.
How do you determine the order of a reaction from data?
Either the differential rate law or the integrated rate law can be used to determine the reaction order from experimental data. Often, the exponents in the rate law are the positive integers: 1 and 2 or even 0. Thus the reactions are zeroth, first, or second order in each reactant.
How do you calculate reaction order from concentration and time?
Take three consecutive points from the concentration versus time data. Calculate ΔyΔx for the first and second points. The concentration is the y value, while time is the x value. Do the same for the second and third point.
What percent is a 5 on AP Chem?

How do you get an A in chemistry?
How To Get An A In Chemistry
- Tip 1: Know the history of Chemistry.
- Tip 2: Learn the Periodic Table using songs and mnemonics.
- Tip 3: The secret to success is using formulas!
- Tip 4: Know how to write Extended Experimental Investigation (EEI) and Extended Response Questions (ERQ)
How do you determine if a reaction is first order or second order?
A zero-order reaction proceeds at a constant rate. A first-order reaction rate depends on the concentration of one of the reactants. A second-order reaction rate is proportional to the square of the concentration of a reactant or the product of the concentration of two reactants.
How do you determine the order of the reaction for each reactant?
The overall reaction order is the sum of the orders with respect to each reactant. If m = 1 and n = 1, the overall order of the reaction is second order (m + n = 1 + 1 = 2). describes a reaction that is first order in H+, first order in OH−, and second order overall.
