For a reaction `X to Y`, the graph of the product concentration (x) versus time (t) came out to be a straight line passing through the origin. Hence and time would be the graph of `(d[X])/(dt)` and the time would be

Options

A. straight line with a negative slope and an intercept on y-axis
B. straight linc with a positive slope and an intercept on y-axis
C. a straight line parallel to x-axis
D. a hyperbola.

Answer

C

Explanation

If product concentration is x.
For a zero reaction `(x)/(t)=k`
Thus graph would be straight line passing through origin. So the given information is for zero order reaction. For a zero order reaction, rate of reaction is constant. Thus, plot of rate vs time, x-axis.
