According to Le Chatelier’s principle, if pressure is increased, then the equilibrium shifts to the side with the fewer number of moles of gas.
Explanation:
- NaCl + AgNO3<------>NaNO3 + AgCl.
- In any reaction a temperature increase uplifts the reaction that absorbs heat which is known as the endothermic reaction.
- The product which absorbs heat, shifts the reaction to the left hand side.
- This shows that the reverse reaction or backward reaction is endothermic.
- if the temperature is increased for an endothermic reaction, essentially a reactant is being added, so the equilibrium shifts toward products.
- Le Chatelier’s principle states that it can be used to predict the behavior of a system due to changes in pressure, temperature, or concentration.
- If the concentration of reactants is increased the reaction is shifted to the right, while increasing the concentration of products will shift the reaction to the left side.
The first one shows greater amplitude because there is more space between the waves. The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position. In a sense, the amplitude is the distance from rest to crest. Similarly, the amplitude can be measured from the rest position to the trough position.
They were created with stone and wood and sometimes even bones, I hope this helped!
Let's assume that CH₄ has ideal gas behavior.
Then we can use ideal gas formula,
PV = nRT
Where, P is the pressure of the gas (Pa), V is the volume of the gas (m³), n is the number of moles of gas (mol), R is the universal gas constant ( 8.314 J mol⁻¹ K⁻¹) and T is temperature in Kelvin.
P = 1 atm = 101325 Pa
V = 1.50 L = 1.50 x 10⁻³ m³
n = ?
R = 8.314 J mol⁻¹ K⁻¹
T = 0 °C = 273 K
By substitution,
101325 Pa x 1.50 x 10⁻³ m³ = n x 8.314 J mol⁻¹ K⁻¹ x 273 K
n = 0.0669 mol
Hence, moles of CH₄ = 0.0669 mol
Moles = mass / molar mass
Molar mass of CH₄ = 16 g mol⁻¹
Mass of CH₄ = moles x molar mass
= 0.0669 mol x 16 g mol⁻¹
= 1.0704 g
Hence, mass of CH₄ in 1.50 L at STP is 1.0704 g
