instantaneous rate

[Rhea Shah 2F]

Why do we use the instantaneous rate instead of the average rate?

[Zoya Mulji 1K]

because it is more accurate since you can get the rate of a reaction at a certain time by taking the slope of a tangent line

[J_CHEN 4I]

The instantaneous rate is for finding the entire area under the curve, while the average rate gives an approximation.

it is more precise because it isn't an average

[Justin Quan 4I]

Since the instantaneous rate of change is the rate of change at a particular point or instant in time. This is better than average rate of change because an instantaneous rate will give you the rate of the reaction at that exact instant in the reaction.

Because it gives the exact slope at a specific time rather than an average of slopes over a range of t values

[anjali41]

The instantaneous rate is used because it refers to the rate at one specific time. In contrast, the average rate occurs over a longer time period, so it is not as precise.

[Jack Riley 4f]

It is more precise for that specific moment in time

[Shail Avasthi 2C]

Since reaction and product concentrations follow smooth curves that are defined by equations, we can easily use the instantaneous rate of change, which will give us a more accurate result than using an average. It also allows us to turn the differential rate laws into the integrated rate laws.

[HuyHa_2H]

The instantaneous rate applies to a specific point in time which is more useful than an average rate as the graph may not be as consistently simple in which the average rate can be very different as to what the actual rate is.

[aishwarya_atmakuri]

Instantaneous rate is more accurate for a specific time, while average gives you the overall rate of the reaction.

[Osvaldo SanchezF -1H]

You would take the instantaneous rate over the average rate because it is more accurate since it is the rate at one specific time instead of that at an interval which would lead to a greater margin of error.

[Rebekah Alfred 1J]

With average rate, there is a larger error because you are treating the curve as a line when taking two points into consideration. However, with instantaneous rate, you are using only one point to get the slope, which results in a more accurate slope.

[Caroline Zepecki]

Instantaneous rate breaks up into infinite intervals, whereas average relies only on the data points you're given so it's far less accurate.

[Jasmine W 1K]

The instantaneous rate is more precise because it isn't an average.

[Lauren Stack 1C]

An instantaneous rate provides an infinite amount of time points that you can measure the rate. It is more accurate than taking the average between two points because you are looking at the exact rate in time, rather than an approximation between two points where the rate in between the two points can be non-constant.

[805329408]

Since the graph is a curve, taking the average rate will treat the graph as a line instead and not account for the curve which an instantaneous rate does.
