table, so we will get the same initial and equilibrium concentrations for each species. Which is the same as the value of x calculated in the R.I.C.E. Through the use of numerical experimentation and 'what if' scenarios, we have a powerful discovery learning tool for students using readily available off-the-shelf software. These interactive spreadsheets (aka - simulations) are used in-class and as out-of-class projects. Step 2: Use the equilibrium concentrations to calculate the value of K c Chemical Excelets: Interactive Excel Spreadsheets for General Chemistry. Table to calculate the equilibrium concentrations of all species = equilibrium concentration of CO 2(g) in mol L -1 To do this, we use a technique called the ICE table calculation. = equilibrium concentration of H 2(g) in mol L -1 Consider the gas phase chemical system represent by the following chemical equation. = equilibrium concentration of CO (g) in mol L -1 = equilibrium concentration of H 2O (g) in mol L -1 (2) What is the relationship between what you know and what you need to find out? N(H 2(g)) (eq) = moles H 2(g) at equilibrium = 0.44 mol N(CO 2(g)) (i) = moles CO 2(g) initially = 1 mol N(H 2(g)) (i) = moles H 2(g) initially = 1 mol

(1) What information (data) have you been given in the question? Insert these expressions for equilibrium concentrations into the R.I.C.E.

concentration of C (g) will increase from 0 mol L -1 to (0 + c x) because C (g) is being produced by the decomposition of A (g).

concentration of B (g) will increase from 0 mol L -1 to (0 + b x) because B (g) is being produced by the decomposition of A (g).

concentration of A (g) will decrease from 1.0 mol L -1 to (1.0 - a x) because A (g) is being consumed during the reaction to produce products B (g) and C (g).

In our example for the decomposition of A (g): Step 5: Use the initial concentration and concentration change expressions to a write an expression for the concentration of each species at equilibrium: Therefore the concentration of A must decrease by the amount ax (- a x), and, the concentrations of B and C must increase by bx (+ b x) and cx (+ c x) respectively. a pollution of 1 gram of benzene in a certain amount of water converts to N A/78.11≈ 7.Note: since initially ONLY reactant A was present (no B, no C), clearly the reaction must proceed in the forward direction to produce products B and C. Using the above calculator you could find that e.g.

It is used in chemistry to keep track of the changes in amount of substance of the reactants and also organize a. Or 1 mole of a substance will contain Avogadro's number of that substance. ICE stands for initial, change, equilibrium. The term ' mole' is defined in that one mole of a substance with a molecular (or atomic) mass of one (1), will have a mass of 1 gram. It is defined to be 1/12 of the mass of one atom of carbon-12 and in older works is also abbreviated as 'amu'.Īlso, important in this field is Avogadro's number (N A) or Avogadro's constant (6.0221 x 10 23). In related terms, another unit of mass often used is Dalton (Da) or unified atomic mass unit (u) when describing atomic masses and molecular masses. Molecular mass or molar mass are used in stoichiometry calculations in chemistry. This Calculator has been tested on Internet Explorer version 6 only,įirefox might not show all fields correctly.
