Question

How we calculate rate of reaction in terms of pressure

Answer 1

Dear student

we knew that ideal gas equation is
PV = nRT (R and T are constant so they can be taken out of the equation)

PV $\infty$ n
$$\begin{gathered} P\infty \frac{n}{V} \\ alsoweknewthat:\frac{No.ofmoles}{Volume}=Concentration \end{gathered}$$

Therefore; P $\infty$ C
Seeing as pressure is directly related to concentration, then we just use the pressure data to find the concentration and then relate that to the concentration change over time to find the rate of reaction.
