Question

The graph plotted between concentration versus time

• A. It gives rate of disappearance of reactant
• B. Rate $=-\frac{d\left[C_{2}-C_{1}\right]}{t_{2}-t_{1}}$
• C. Both(1) & (2)
• D. It predicts the order of reaction

Answer 1

Answer: (C)

In given graph concentration decreases with time which shows that it is the graph of reactant because concentration of reactant decreases as time increases. So,
