Solution
For first order decomposition of N2O5, rate law is given by rate, r =k[N2O5]
On plotting rate on y-axis and concn[N2O5] on x-axis and then comparing it with y = mx + c, we get a line starting from origin with slope'k'. Its positive slope suggests that line is going up. Hence graph shown in option (d) is the correct choice.
The rate constant of a reaction is 3.00 × 103 L mol-1 sec-1.The order of this reaction will be:
-
Solution
In the following first order competing reactions
X + reagent ⟶ product
Y + reagent ⟶ product
The ratio of \(\frac{k_{1}}{k_{2}}\) if only 50% of Y will have been reacted when 94% of X has been reacted is
-
Solution

Solution
The order w.r.t. I2 is zero because the rate is not dependent on the concentration of I2.
