No lab techniques are listed for this simulation.

Equilibrium describes the state of a reversible reaction, in which the forward and backward reactions happen at equal rates. In this state, the concentrations of reactants and products are stable and do not change over time. Thus, there are no net changes in the concentrations of the reactant(s) and product(s). Such a state is known as dynamic equilibrium. It is a particular example of a system in a steady state.

Thermodynamics

In thermodynamics a closed system is in thermodynamic equilibrium when reactions occur at such rates that the composition of the mixture does not change with time. Reactions do in fact occur, sometimes vigorously, but to such an extent that changes in composition cannot be observed.

Help out a famous scientist

In chemistry there are several different types of equilibria: thermodynamic equilibrium, diffusive equilibrium, thermal equilibrium, and many more. In the Equilibrium Simulation, you will learn about the general chemical equilibrium and help a famous scientist to prevent a global famine. You will learn how to influence and predict the directionality of reversible reactions in the lab.

Will you be able to apply your knowledge to increase the yields of fertilizer for the crops?

## For Science Programs Providing a Learning Advantage

Associate Professor
North Dakota State College of Science

“They did the simulation at home, then completed the in-person lab within 30 minutes, no questions asked, and passed the quiz with flying colors.”

Lewis Mattin
PhD
Lecturer in Human Physiology
University of Westminster

"I saw some of the students who clearly didn’t necessarily like sitting there reading a book discover they could turn on Labster and keep up with the rest of the class because it spoke to them.

Melody McGill
Curriculum Coordinator
Modesto City Schools

"Having something that's engaging for the students gives teachers that opportunity to breathe and get excited again. Because they're seeing the kids light up, they're seeing the kids engage with content."

Kyle Hammon
Wenatchee Valley College

"The question always is, ‘Can we demonstrate that the students are meeting course outcomes?’ Check! We can do that.”

Dr. Melody Esfandiari
Chemistry Lecturer
San José State University

"We surveyed over 400 students. More than 90% thought Labster was easy to navigate, and that it was fun, but more importantly, most of them felt confident that they could execute the labs in person. And that confidence is a big deal."

Dr. Stuart Goodall
Lecturer
Northumbria University

“The Labster simulations get students to do things, and they're not just sitting there consuming a webinar where their mind can drift. They become an active participant in that learning experience.”
