## What is instantaneous rate in chemistry?

The instantaneous rate is the rate of a reaction at any particular point in time, a period of time that is so short that the concentrations of reactants and products change by a negligible amount. The initial rate is the instantaneous rate of reaction as it starts (as product just begins to form).

## What is instantaneous rate on a graph?

The instantaneous rate is the rate at a particular time. It is determined by finding the slope of the tangent to the concentration vs time curve at that time. The initial rate is the instantaneous rate at the very beginning of a reaction.

**How do you describe the rate of reaction from a graph?**

Graphs. The rate of reaction can be analysed by plotting a graph of mass or volume of product formed against time. The gradient of the line is equal to the rate of reaction: the steeper the line, the greater the rate of reaction.

### How do you find instantaneous rate in chemistry?

An instantaneous rate is the rate at some instant in time. An instantaneous rate is a differential rate: -d[reactant]/dt or d[product]/dt. We determine an instantaneous rate at time t: by calculating the negative of the slope of the curve of concentration of a reactant versus time at time t.

### Why is instantaneous rate better than average?

Why is instantaneous rate preferred over average rate of reaction? The rate of reaction at any time depends upon one of the reactants at that time which is not constant but goes on decreasing with time continuously. Therefore, instantaneously rate gives more correct information at that time as compared to average rate.

**How do you explain the rate of a reaction?**

reaction rate, in chemistry, the speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.

#### How do you describe the rate of reaction?

The reaction rate or rate of reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time.

#### What derivative is instantaneous rate of change?

The derivative, f (a) is the instantaneous rate of change of y = f(x) with respect to x when x = a. When the instantaneous rate of change is large at x1, the y-vlaues on the curve are changing rapidly and the tangent has a large slope.

**How do you find instantaneous rate of change with derivatives?**

You can find the instantaneous rate of change of a function at a point by finding the derivative of that function and plugging in the x -value of the point.

## Which is the best definition of instantaneous rate?

Instantaneous rate is the rate of a chemical reaction that is measured as the change of the concentration of reactants or products during a known time period.

## What is the instantaneous rate of reaction on a graph?

A graph of the concentration [P] vs. time t is usually not a straight line but a curve. The instantaneous rate of reaction is the slope of the line (the tangent to the curve) at any time t.

**How is the instantaneous rate of change determined?**

Instantaneous Rate: Rate decreases over time. Therefore instantaneous rate, the rate at any given time, is sometimes used. The instantaneous rate can be determined from a tangent line at the relevant instant of time on a graph of concentration versus time. A comparison of the methods demonstrates the strengths and weakness of each:
