73.40%
To express the efficiency of a reaction, you can calculate the percent yield using this formula: %yield = (actual yield/theoretical yield) x 100.
Answer: 41.46 L
Explanation:
La ecuación que describe relación entre presión, volumen, temperatura y la cantidad (en moles)
de un gas ideal es:
PV = nRT
Donde: P = Presión absoluta
, V= Volumen , n = Moles de gas
, R = Constante universal de los gases ideales, T = Temperatura absoluta,
R = 0.082 L. atm/mol. °K
V = nRT/P
Calculanting n
n = mass/ molecular mass
<h3>n = 4 g / 2g. mol⁻¹</h3><h3>n = 2 mol</h3><h3>T =25⁰ + 273 ⁰K = 298 ⁰K</h3><h3>V = (2 mol ₓ0.082 L. atm / mol.°K x 298 ⁰K) / 1.18 atm = 41.46 L</h3>
Based on Le Chatelier's principle, the following factors will affect the chemical equilibrium
1) Temperature
2) Pressure
3) concentration
4) catalyst
The given equilibrium involves
H2(g) + I2(g) → 2HI(g)
The reactants are H2 and I2 while the product is HI. The equilibrium will be affected by changes in the concentration of H2, I2 or HI.
However, the equilibrium will not be affected by the addition of N2 since it is not involved in the reaction
