The chemical equation corresponding to the hydrolysis reaction can be written: R-CI+ H2O →R-OH+CI¯+ H* Let's call a the initial concentration in 2-chloro-2-methyl-butane and x the concentration of hydrochloric acid that is formed at time t. Water remains in large excess all over the course of the reaction. Then one can write: R-l + H20 Cexcess) > R-OH +d-+ht at to, a at t>0, a-se at tD, a a a 05: Recall the Arrhenius law and explain the meaning and unit of the individual terms.

By using collision theory calculate the activation energy of a reaction having two reactants A and B and the product is C. The value of the universal rate constant is 8.314J/mol*K.When the reaction is happening at different temperatures 350K and 700K , the ratio of rate constant is 5. (Gpt/ai wrong answer not allowed)
Suppose that for the reaction K + L------->M, you monitorthe production of M over time, and then plot the followinggraph from your data: (a) Is the reaction occurring at a constant rate from t = 0to t = 15 min? (b) Is the reaction completed at t = 15min? (c) Suppose the reaction as plotted here were startedwith 0.20 mol K and 0.40 mol L. After 30 min, an additional0.20 mol K are added to the reaction mixture.Which of the following correctly describes how the plotwould look from t = 30 min to t = 60 min? (i) [M] wouldremain at the same constant value it has at t = 30 min,(ii) [M] would increase with the same slope as t = 0 to15 min, until t = 45 min at which point the plot becomeshorizontal again, or (iii) [M] decreases and reaches0 at t = 45 min.
