Answer:
Second order
Explanation:
Given that:
When the reaction A → B + C is studied, a plot 1/[A]t vs. time gives a straight line with a positive slope.
From the integration method for the second order of reaction.
Suppose that:
rate = k₂[A]²
∴
Therefore, a plot of the linear function versus t will be linear with a positive slope k₂ and the intercept on the concentration axis will be
The linear plot for a second order reaction can be seen in theimage attached below.
Answer : The correct expression will be:
Explanation :
The chemical reactions are :
(1)
(2)
The final chemical reaction is :
Now we have to calculate the value of for the final reaction.
Now equation 1 is multiply by 2 and then add both the reaction we get the value of 'K'.
If the equation is multiplied by a factor of '2', the equilibrium constant will be the square of the equilibrium constant of initial reaction.
If the two equations are added then equilibrium constant will be multiplied.
Thus, the value of 'K' will be:
