For a certain reaction R Product, the plot of concentration [R] vs time has a negative slope as shown. The order of reaction is :

Step-by-step solution

From the given graph, the plot of concentration [R] versus time t is a straight line with a negative slope. The equation for this straight line can be written as: y = mx + c [R] = ( slope ) t + intercept Given that the intercept is [R₀] and the slope is -k , the equation becomes: [R] = -kt + [R₀] This equation represents the integrated rate law for a zero-order reaction. For a zero-order reaction, the rate of reaction is independent of the concentration of the reactant: Rate = - d[R] dt = k[R]^0 = k Integrating bot
