Question

What is the graph (concentration vs time) of zero order reaction look like?

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

For zero order reaction
Rate = K
$\frac{dc}{dt}=K$ Integrating on both sides
$Co–C=Kt\to C=Co-Kt$
It is in the form of y = mx + C and slope is negative. (-K).
