Can rate be in molarity per second
Did you know?
WebUnits of rate are molar per second, and the units of concentration are always going to be molar. So now we know that the units of k times molar equals molar per second. So we have molar on both sides, so we don't have to worry about that, but we're missing a one … WebSo in our first experiment, the concentration of B is one molar and the rate is .01 molar per second. And then we change the concentration of B to two molar. Right, we double the concentration of B while holding the concentration of A constant. And we observe the …
WebGiven the data below of the concentration of compound A for the reaction A - B, what is the average rate of disappearance (in units of molarity per second) of A from 100. seconds to 400 seconds? Time 300 400 500 100 200 600 0 (s) [A] 0.0040 0.811 0.331 0.135 0.055 0.023 0.009 (M) Report your answer in scientific notation Your answer should have two Hence the rate constant must have units of reciprocal seconds (s −1) to have units of moles per liter per second for the reaction rate: M·s −1 = M/s. B The only concentration in the rate law is that of cyclopropane, and its exponent is 1. This means that the reaction is first order in cyclopropane.
WebThe molar rate of transfer of component A, per unit area, in a mixture of A and B is given by Fick's Law, viz. (1) where Na = molar rate of diffusion/unit area, DAB = diffusivity of A in B, CA = molar concentration of A, y = distance in direction of diffusion. Similarly, the rate of … WebExpress the rate in molarity per second to three significant figures. O ΑΣφ ? rate = 2.87 M/s 2NO (g) + O2 (g) + 2NO2 (g) For the above reaction, the following data were collected for the rate of disappearance of NO in the reaction: Initial Rate Experiment [NO] (M) [02] (M) (M/s) Show transcribed image text Expert Answer 100% (2 ratings)
WebFeb 2, 2024 · For the units of the reaction rate to be moles per liter per second (M/s), the units of a second-order rate constant must be the inverse (M −1 ·s −1 ). Because the units of molarity are expressed as mol/L, the unit of the rate constant can also be …
