General Chemistry 2: Rates of Reaction

The initial concentration of hydroiodic acid is 100 mmol/L but after 500 s it is 17 mmol/L. What is the rate? (note the products of this reaction are hydrogen and iodine gas)

The following initial rate data was collected for the reaction, A + 2B $\longrightarrow$ products

B. Find the rate constant

When cyclopropane is heated to 500 $^\circ$C it changes to propene. The following data was obtained from experiment:

Confirm that the reaction is 1st order and calculate the rate constant.

An isotope of phosphorous, $^{32}$P, is radioactive and undergoes beta decay with a half life of 14.3 days. How long would it take for 99% of a sample of this isotope to decay?

For a given reaction, the reaction rate exactly doubles when the temperature is raised from 293 K to 304 K. Calculate the activation energy.

For the mechanism proposed below, determine the overall rate law for k$_1$ < k$_2$, k$_1$ > k$_2$

$2~NO~+~2 H_2~\longrightarrow~2~H_2O~+~N_2~~{overall}$

$2~NO+~H_2~\mathop{\leftrightharpoons}^{k_1}_{k_{-1}}~N_2O~+~H_2O$

$N_2O~+~H_2~\xrightarrow{k_2}~N_2~+~H_2O$

For the mechanism below, determine the overall rate law.

$2~NO~+~Br_2~\longrightarrow~2~NOBr~~{overall}$

$NO+~Br_2~\mathop{\leftrightharpoons}^{k_1}_{k_{-1}}~NOBr_2$

$NOBr_2~+~NO~\xrightarrow{k_2}~2NOBr$

Find the rate law for the following reaction mechanism using the pseudo(quasi) steady state hypothesis

$A + B~\longrightarrow~C$

$C~\longrightarrow~D$
