Average Rate of Reaction

Q. write the statement for the average rate for this chemical reaction 3A + B ---> C + 3 D a) Average rate would the answer be - A-delta/ 3 time = - delta b/ time = delta c/ delta T = d delta/ 3 time?? because my professor put 1/2 and 1/3 as an answer but in Jules video,​ he said this option works as well I just want to double-check

Average Rate of Reaction

Q. Consider this hypothetical reaction in an aqueous solution at 25 C: A(aq) -> B(aq). A flask charged with 0.065 mol of A in a total volume of 100.0 mL. The following experimental data are collected: What is the average rate of appearance of B in units of mol/(Ls) between t = 10 min and t = 30 min (at 25 C)? Assume that the volume of the solution is constant.

Average Rate of Reaction

Q. How is the rate at which ozone disappears related to the rate at which oxygen appears in the following reaction? 2 O 3 (g) ---> 3 O 2 (g) If the rate at which O 2 appears is 6.0×10 ^-5 M/s at a particular instant, at what rate is O 3 disappearing at this same time?

Average Rate of Reaction

Q. Just as the depletion of stratospheric ozone threatens life on Earth today, its accumulation was one of the crucial processes that allowed life to develop in prehistoric times: 3O2(g) -> 2O3(g) At a given instant, the reaction rate in terms of [O2] is 2.17 x 10^-5 mol/L*s. What is it in terms of [O3]? Enter your answer in scientific notation.

Average Rate of Reaction

Q. The decomposition of NOBr is studied manometrically because the number of moles of gas changes; it cannot be studied colorimetrically because both NOBr and Br2 are reddish-brown. 2NOBr(g) -> 2NO(g) + Br2(g) Use the data below to make the following determination: (a) the average rate of decomposition of NOBr over the entire experiment. (b) the average rate of decomposition of NOBr between 2.00 and 4.00 seconds. The rates of decomposition of NOBr are

Average Rate of Reaction

Q. Express the rate of reaction in terms of the change in concentration of each of the reactant and products: 2D(g) + 3E(g) + F(g) -> 2G(g) + H(g) When [D] is decreasing at 0.88 mol/L*s, how fast is [H] increasing?
