Interpretation: Defining the chemical reversible reaction. Examining the question whether all
Concept introduction:A reversible chemical reaction can be defined as a reaction that can go in both forward and backward directions. The reactants can change into the products, and the products can change back into the reactants.This keeps on happening until it reaches equilibrium.
Equilibrium constant
The expression for equilibrium constant
Answer to Problem 12A
In principle all chemical reactions are reversible.
Yes, some reactions are more likely to occur in one direction.
Explanation of Solution
All chemical reactions are reversible, at least in principle. Equilibrium is dynamic in nature; it may appear that no change is happening. But actually, both forward and backward reaction occurs at same rate. Reactants get combined to form the products and the products combe to form the reactants.
Some chemical reactions are likely to occur in one direction. These reactions are called irreversible reactions.Irreversible reactions are marked by their high value of equilibrium constant
In a complete combustion reaction, fuel (generally hydrocarbons) and oxygen reacts to form carbon dioxide and water. These two products cannot react to regenerate the fuel and oxygen, so the reaction is irreversible.
In principle, all chemical reactions are reversible.
Yes, some reactions are more likely to occur in one direction.

- There is an instrument in Johnson 334 that measures total-reflectance x-ray fluorescence (TXRF) to do elemental analysis (i.e., determine what elements are present in a sample). A researcher is preparing a to measure calcium content in a series of well water samples by TXRF with an internal standard of vanadium (atomic symbol: V). She has prepared a series of standard solutions to ensure a linear instrument response over the expected Ca concentration range of 40-80 ppm. The concentrations of Ca and V (ppm) and the instrument response (peak area, arbitrary units) are shown below. Also included is a sample spectrum. Equation 1 describes the response factor, K, relating the analyte signal (SA) and the standard signal (SIS) to their respective concentrations (CA and CIS).
