When the reaction A → B + C is studied, a plot 1/[A]t vs. time gives a straight line with a positive slope. What is the order of the reaction?

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.

so what is the problem with your lab report and whats the subject of the lab report? i will you
