The kinetic study of a reaction like v A P at 300 K provides the following curve, where concentration is taken in mol dm ⁻³ and time in min. Identify the correct order (n) and rate constant (k)

Step-by-step solution

From the given graph Slope = ( rate )^ 1 / 2 [A] =4 rate (r)=k[A]^ n Where, k= rate constant [A]= concentration at time t (in min). n= order. According to the graph (n=2) k= rate [A]^ n =[4]²=16 Hence, n=2 and k=16.0 dm ³ mol ⁻¹ ⁻¹ and option (d) is the correct answer.
