# What is instantaneous rate of reaction? and how we can determine it?

##### 1 Answer

#### Answer:

Here's what I get.

#### Explanation:

**The definition**

Suppose we have a reaction that forms a product

A graph of the concentration

The **instantaneous rate of reaction** is the slope of the line (the tangent to the curve) at any time

(From SPM Chemistry)

**How do we determine it?**

We draw the best tangent to the line that we can and extend it to convenient points on the axis that will make it easy to calculate the value of

For example, the graph below shows the volume of carbon dioxide released over time in a chemical reaction. Find the instantaneous rate of reaction at t = 40 s.
