Question 11 5 pts
Nitrosyl chloride, NOCl, decomposes to NO and Cl2.
2NOCl (g) ----> 2NO (g) + Cl2 (g)
Determine the overall order and rate constant "k" for this
reaction from the following data:

0.30
Rate (M/h)
8.0 x 10–10

Q1)
part A:
Consider the decomposition of NOCl: 2NOCl(g) → 2NO(g) +
Cl2(g)
During the decomposition, the concentration of cyclopropane is
measured. By graphing [NOCl] vs. time, ln[NOCl] vs. time and
1/[NOCl] vs. time, the plot of 1/[NOCl] vs. time gives a straight
line with a slope of 9.98 x 10-2 at 129oC.
(a) What is the reaction order for the decomposition of
NOCl.
(b) Calculate the rate constant of the reaction.
(c) If the initial concentration of NOCl(g) is...

The decomposition of nitrosyl bromide
is a second-order reaction: NOBr
(g) à NO (g) +
½ Br2(g)
If the initial concentration of NOBr
is 0.250 M, how much heat is evolved or absorbed per liter of
solution in one minute? The rate constant is 0.80
L/(mol.s). The heats of formation are +82.2 kJ/mol for
NOBr, +90.2 kJ/mol for NO, and +30.9 kJ/mol for Br2 as a
gas.

The following shows the gas phase decomposition of hydrogen
peroxide (H2O2) at 400 °C: 2H2O2(g)2H2O(g) + O2(g)
This reaction is second order in H2O2 with a rate constant of
0.650 M-1s-1 and the initial concentration of H2O2 is 0.600
M.
a) What is the concentration of H2O2 after 40 second? (extra
credit) What is the concentration of O2
at that time?
b) Calculate the first and second half-life of this reaction. Are
the values same or different?

c). 1.01 mol/L concentration of all three gases
Please show work and don't just solve the top problem. I need
all three and I don't know how to correctly solve either of
them!!

Given the following reactions of nitrosyl chloride (NOCl),
calculate the ∆H°rxn, in kilojoules per mole, for the third
reaction. Enter your answer to the tenths place. Don’t forget the
sign! 2NOCl(g) ⟶ 2NO(g) + Cl2 (g) ΔHrxn ° = +79.2 kJ mol ⁄
NOCl(g) + 1 2 O2 (g) ⟶ NO2Cl(g) ΔHrxn ° = -39.1 kJ mol ⁄
2NO(g) + Cl2 (g) + O2 (g) ⟶ 2NO2Cl(g)
