Which of the following is not a possible unit for the rate constant of a reaction?
Aqueous hydrogen peroxide decomposes to form oxygen and water. The concentration of a hydrogen peroxide solution was measured at regular time intervals during this reaction, as shown in the table.
By plotting suitable functions of the tabulated data, determine the appropriate unit for the rate constant of this reaction.
Expressing concentrations in molars and time in hours, estimate, to 3 significant figures, the numerical value of the rate constant for this reaction.
Nitroglycerine decomposes via a first-order process. Solutions of nitroglycerine with different initial concentrations were heated to . After a certain time, the percentage of compound reacted was measured for each solution, as shown in the table.
|Initial Concentration (M)||Time (s)||Nitroglycerine Reacted (\%)|
By calculating the rate constants for each of these reactions, estimate the mean rate constant for the decomposition of nitroglycerine at .
