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
1-The rate constant of a chemical reaction was measured at several temperature values and a plot of ln k (on the y-axis) was plotted against 1/T (on the x-axis, temperature was measured in Kelvin). If the slope of the plot was -9.21 x 103 K and the y-intercept was 13.0, what is the activation energy (EA) of the reaction in kJ mol-1? 2-In an enzyme-catalyzed reaction, the rate of the reaction depends on which of the following at very low...
If a zero order reaction has a rate constant k of 0.0416Mmin and an initial concentration of 2.29 M, what will be its concentration after 20.0 minutes? Your answer should have three significant figures.
- 1 At a certain temperature this reaction follows second-order kinetics with a rate constant of 11.7 M is : 2NH3(g) → N2(g) + 3H2(g) Suppose a vessel contains NH, at a concentration of 0.670 M. Calculate the concentration of NH, in the vessel 0.510 seconds later. You may assume no other reaction is important. Round your answer to 2 significant digits. x 6 ?
