Question

in concentration verses time graph, instantaneous rate is equal to the​

Answer 1

Answer:

Considering an example

A⟶B

The slope of graph at any time t will be:

⇒

dt

−d[A]

t

dt

−d[A]

t

is the rate of change of reactant at time t.

⇒ which is the instantaneous rate of reaction at time t.

Option C is correct.

Answer 2

In the concentration versus time graph, the rate is equal to the​ slope of the graph.

• For a chemical reaction, the rate gives the rate of formation of the product or the rate of disappearance of the reactant.

• For a reaction A+ B → C + D, the rate is $-\frac{d[A]}{dt}$ or $-\frac{d[B]}{dt}$ or $\frac{d[C] }{dt}$ or $\frac{d[D]}{dt}$.
• The rate is also equal to the slope of the concentration-time graph.
• The slope of a graph = tan ∅. Here ∅ is the angle that the tangent to the graph makes with the time axis.
