How do you find the rate of decomposition?
Key Points
- Reaction rate is calculated using the formula rate = Δ[C]/Δt, where Δ[C] is the change in product concentration during time period Δt.
- The rate of reaction can be observed by watching the disappearance of a reactant or the appearance of a product over time.

How can you determine the rate law of the following reaction 2n2o5 2no2 O2?
What is the half-life of the decomposition?
The half-life of a reaction is the time required for the reactant concentration to decrease to one-half its initial value. The half-life of a first-order reaction is a constant that is related to the rate constant for the reaction: t1/2 = 0.693/k. Radioactive decay reactions are first-order reactions.
What is the half-life of a radioactive substance?
half-life, in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time interval required for the number of disintegrations per second of a radioactive …
What is the rate of decomposition of NO2?
For the reaction: 2 NO2(g) 2NO(g) + O2(g), the rate law is Rate = k[NO2]2. That is, the rate of the decomposition of NO2 is second order with respect to [NO2]. Therefore, the rate will quadruple if [NO2] is doubled.
Is the concentration of N2O5 a function of time?
Figure 12.3: A plot of the concentration of N2O5 is a function of time for the reaction: 2N2O5(soln) º4NO2(soln) + O2(g) (at 45ºC). Note that the reaction rate at [N2O5] = 0.90 Mis twice that at [N2O5] = 0.45 M.
How to graph the rate of a reaction?
Graph the data as concentration versus t, ln concentration versus t, and 1/concentration versus t. Then determine the reaction order in C 4 H 6, the rate law, and the rate constant for the reaction. For a zeroth-order reaction, a plot of the concentration of any reactant versus time is a straight line with a slope of − k.
Where does the decomposition of a gas take place?
In the case of the gas, the likelihood collisions resulting in reaction increases Factors Affectin g Reaction RatesFigure 12.8: The decomposition reaction: 2N2O(g) º 2N2(g) + O2(g) takes place on a platinum surface. 5
