Rate Law Expression
2NOCl(g) → 2NO(g) + Cl2(g)
What happens to the rate of consumption of NOCl when the concentration of NOCl is quadrupled?
What is the rate increases by a factor of 16.
At 225°C, the reaction for NO2 and CO is:
NO2(g) + CO(g) → 2NO(g) + CO2(g)
is second order in NO2 and second order overall. What is the rate law expression for this reaction?
What is rate = k[NO2]^2
2NO(g) + 2H2(g) → 2H2O(g) + N2(g); find the rate
Exp/[H2]0(M)/[NO]0(M)/Initial rate (M/s)
1 0.212 0.136 0.0248
2 0.212 0.272 0.0991
3 0.424 0.272 0.198
What is rate= k[NO]2[H2]
This follows zero order kinetics with an average rate constant of 3.26 × 10–4 M/s.
CH3CH2OH(aq.) → products
When a person hits the legal 0.08% blood alcohol concentration limit (1.74 × 10–3 M), what is the rate of consumption of CH3CH2OH? Hint: set up the rate
What is 3.26 × 10–4 M/s?
Reaction is first order in CH3OCH3 with a rate constant of 4.00 × 10–4 s–1:
CH3OCH3(g) → CH4(g) + H2(g) + CO(g)
If initial concentration CH3OCH3 is 0.105 M, how much time would have passed if the concentration of CH3OCH3 were to drop to 0.0288 M?
What is 3.24 × 10^3 s
4PH3(g) → P4(l) + 6H2(g)
In a typical reaction at 120°C, it was determined that the rate of disappearance of PH3 is 5.83 × 10–4 M/s What is the rate of formation of H2?
8.75 × 10–4 M/s
