zero order reaction

Question

For a zero-order reaction, the plot of concentration vs time is:

RankGuru · Accepted Answer

For a **Zero-Order Reaction**, the rate is independent of the reactant concentration:
$	ext{Rate} = k [A]^0 = k \implies -\frac{d[A]}{dt} = k$
Integrating this differential equation:
$[A]_t = [A]_0 - kt$
- Comparing with $y = mx + c$:
- $y$: $[A]_t$ (Concentration at time $t$)
- $x$: $t$ (Time)
- $m$: $-k$ (Slope is negative)
- Thus, the graph is a **straight line with a negative slope**.
