Confunsed about reactions in equilibrium

Click For Summary
SUMMARY

In the discussion, users explore the equilibrium of the reaction 1A + 1B <-> 1C + 1D, starting with 1 mol of each reactant and product. The equilibrium constant (Keq) is given as 4. The equation defining Keq is expressed as Keq = [C][D]/[A][B]. By applying this equation alongside the initial conditions, users can determine the molar amounts of each substance at equilibrium.

PREREQUISITES
  • Understanding of chemical equilibrium concepts
  • Familiarity with equilibrium constants (Keq)
  • Basic algebra for solving equations
  • Knowledge of stoichiometry in chemical reactions
NEXT STEPS
  • Review the principles of chemical equilibrium and Le Chatelier's principle
  • Study how to calculate equilibrium concentrations using the ICE table method
  • Learn about the significance of equilibrium constants in chemical reactions
  • Explore examples of reactions with different Keq values to understand their implications
USEFUL FOR

Chemistry students, educators, and anyone interested in mastering the concepts of chemical equilibrium and reaction dynamics.

Hey guys, in a reaction like 1A + 1B <-> 1C + 1D, which starts with 1 mol of each molecule (A,B,C,D), how can I find out how many mols will be remaining in equilibrium state?

knowing that the Keq is equal to 4

Write out the equation that defines Keq. Hopefully you will see that, at least together with a very simple and elementary principle of chemistry (as well as of physics) you have all the information needed to solve the problem.
