The value of K, for the decomposition of ammonia at 127 °C is 2.27x10⁻⁵
Understanding Equilibrium ConstantThe Equilibrium Constant is denoted by K and it is a quantitative measure of the extent to which a chemical reaction reaches equilibrium.
It is defined as the ratio of the concentrations (or partial pressures) of the products to the concentrations (or partial pressures) of the reactants, with each concentration or partial pressure raised to a power equal to its stoichiometric coefficient in the balanced chemical equation.
For a general chemical equation:
aA + bB ⇌ cC + dD
The equilibrium constant expression is written as:
K = [tex]\frac{[C]^c[D]^d}{[A]^a[B]^b}[/tex]
where [A], [B], [C], and [D] represent the molar concentrations (or partial pressures) of the reactants and products at equilibrium, and a, b, c, and d represent their stoichiometric coefficients in the balanced chemical equation.
Back to our main question, the equilibrium constant for the reverse reaction (decomposition of ammonia) can be obtained from the equilibrium constant of the forward reaction (synthesis of ammonia) using the relationship:
Kreverse = 1 / Kforward
where Kforward is the equilibrium constant for the synthesis of ammonia.
Substituting the given value of Kforward:
Kreverse = 1 / 44005 = 0.0000227
In standard form, we have 2.27x10⁻⁵

What inference can be drawn from the graph? a graph of reactant and product concentration vs. time; a red curve shows the reactant decreasing and a blue curve shows the product concentration increasing over time; the two curves do not intersect; the chemical equation shows A + B reacting to produce C + D A. The reaction between A and B is reactant favored. B. The amount of product is greater than the amount of reactant. C. The reaction uses all its reactants to form products. D. The reaction reaches equilibrium at 1.5 seconds. E. The amount of reactants is highest at equilibrium.
The reaction between A and B is reactant favored. This inference can be drawn from the graph.
Chemical reactions occur all around us, including in our body's digestion of food and the creation of the sunlight's light. Understanding both chemical and physical alterations is crucial before starting any chemical reactions. The best illustration of a chemical and physical alteration is a burning candle.

Based on the information, the solubility product of AgCl is 6.91 × 10^-10.
How to explain the informationThe common ion effect concerns the decrease in solubility of a salt when it comes into contact with another compound containing an identical ion within its make-up. This phenomenon is caused by the dependetics that arise from this shared element, which results in a decreasing amount of ions required for dissolving said salt. An illustrative instance is seen when observing the effects of calcium chloride (CaCl2) on calcium sulfate (CsSO4).
Named reactions constitute a subclass of chemical interchanges widely used within organic chemistry. These yield profound utilization due to their notorious titles attributed to notable scientists or related to other respective exploits; they are thus named following mannerisms peculiar to the substance itself.
