Explanation To calculate the rate law, we know that, • In a reaction of zero order the curve of ratevs PA is a horizontal line • In a reaction of first order the curve of rate vs PA is a line. The slope of this curve is the rate constant (K). • In a reaction of second order the curve of rate vs PA is a parabola. P 2 is the partial pressure The total pressure is equal to the sum of the partial pressure of each of the gaseous components of the gas mixture.
