The rate coefficient for a chemical reaction is 4.4 x 10-351 If the initial reactant concentration is 0.9 mol dm, what will the concentration (in mol dm) be after 60 seconds? Express your answer in mol dm, correct to three decimal places. Please do not include the correct units (mol dm) in your answer.
A second order reaction where the starting reactant concentration is 0.0963 M has a measured rate constant of 0.70 M/s at 10 oC. What is the concentration of the reactant after 36.0 seconds? - report your answer in three significant figures - do not write your answer in scientific notation - do not include units
The integrated rate law allows chemists to predict the reactant concentration after a certain amount of time, or the time it would take for a certain concentration to be reached. The integrated rate law for a first-order reaction is: [A]=[A]0e−kt Now say we are particularly interested in the time it would take for the concentration to become one-half of its initial value. Then we could substitute [A]02 for [A] and rearrange the equation to: t1/2=0.693k This equation calculates the time...
Referen The initial concentration of the reactant in a first-order reaction A → products is 0.528 mol/L and the half-life is 27.0 s. (a) Calculate the concentration of the reactant (in mol/L) 54.0 s after initiation of the reaction. moll (b) How long (in s) would it take for the concentration of the reactant to drop to one eighth its initial value? (e) How long (ins) would it take for the concentration of the reactant to drop to 0.0330 mol/L?...
The integrated rate law allow chemists to predict the reactant concentration after a certain amount of time, or the time it would take for a certain concentration to be reached. The integrated rate law for a first-order reaction is: [A] = [A]oe -Rt Now say we are particularly interested in the time it would take for the concentration to become one-half of its initial value. Then we could substitute Z" for [A] and rearrange the equation to: A) 1/2= 0093...
