उत्तर
The slope in the plot of [R] Vs. time for a zero-order reaction is −k.
Explanation:
For the reaction, \[\ce{R -> Products}\]
The integrated zero-order rate equation is [R] = −kt + [R0]
Comparing with the equation of a straight line, y = mx + c, if we plot [R] against t, we get a straight line with slope = −k and intercept equal to [R0]·
