# Representing the Rate of Production?

• TheExibo
You do not mention a unit of any of the reactants, but I guess that is implicit in the rate law equation.

## Homework Statement

Nitric oxide and oxygen gases react to form nitrogen dioxide gas in the reaction 2NO + O2 -> 2NO2

Write a mathematical expression to represent the rate of production of nitrogen dioxide: 4.0x10-3mol/(L*s)

r=k[X]m[Y]n

## The Attempt at a Solution

Not really sure where to start off.

Something is missing here.

Maybe you don't understand what the question is - nor do we - is this verbatim and from where?

Maybe all they want is d[NO2]/dt = - d[NO]/dt = -½ d[O2]/dt = 4.0 X 10-3

which you did not write because it was too obvious?

I would argue even just $r=4.0 \times 10^{-3} \frac {mol}{L \times s}$ qualifies as a correct answer

Yes but sometimes it is just as well to show off a bit.

## 1. What is the rate of production?

The rate of production refers to the amount of a product or substance that is produced per unit of time. It is often measured in units such as kilograms per hour or liters per day.

## 2. How is the rate of production calculated?

The rate of production is calculated by dividing the amount of a product or substance produced by the time it took to produce it. For example, if 100 kilograms of a product were produced in 2 hours, the rate of production would be 50 kilograms per hour.

## 3. Why is it important to represent the rate of production?

Representing the rate of production allows us to track the efficiency of a production process and make improvements if necessary. It also helps us to make predictions about future production and plan accordingly.

## 4. What are some common ways to represent the rate of production?

The rate of production can be represented graphically, with a line or bar graph showing the amount of product produced over time. It can also be represented numerically, with a table or equation showing the rate of production at different time intervals.

## 5. How can the rate of production be increased?

The rate of production can be increased by improving the efficiency of the production process, using more advanced technology, increasing the number of workers, or optimizing the use of resources. It can also be increased by identifying and eliminating any bottlenecks in the production process.
