What happens to the entropy in the reaction I2 s I2 g?
The entropy of the system increases during the sublimation of I2(s) to I2(g) because the randomness and disorder of the gas phase is higher compared to the solid phase. Therefore, the entropy of the reaction is positive.
How does entropy change in gas reactions?
Reactions that increase the moles of gas will increase in entropy.
What happens to the entropy in the reaction l2(s) l2(g)?
The entropy increases, as going from a solid to a gas increases disorder or randomness in the system. This is because gases have more freedom of movement and energy compared to solids.
What happens to the entropy in the reaction l2(s)l2(g)?
The entropy increases in this reaction, as the solid reactant (I2(s)) is becoming a gas (I2(g)), which represents a higher degree of disorder and randomness on a molecular level. The increased entropy contributes to the spontaneity of the reaction.
What describes the entropy change of gas reaction?
if there is an increase in the number of gas molecules , then ^S > 0
What happens to liquids when are heated?
they turn into gas
What happens to a particle in a gas when heated?
It moves Faster.
What happens to gases when heated?
When a noble gas is heated, its molecules move faster (this is the same as saying that the gas heats up).
What happens to the speed of gas when heated?
The speed of the gas particles will increase as they are heated. That is why the pressure in a container increases. The particles are hitting the walls of the container with more force as they are heated.
What does most matter increase in when heated?
entropy and energy
What happens as a solution becomes diluted in entropy?
Its entropy increases.
What happens to the entropy in the reaction I2 s I2 g?
The entropy of the system increases during the sublimation of I2(s) to I2(g) because the randomness and disorder of the gas phase is higher compared to the solid phase. Therefore, the entropy of the reaction is positive.
What happens when gas is heated?
it expands and/or its pressure rises, depending on conditions.
What happens to the pressure of gas when it is heated at a constant heat?
The pressure is higher.
When happens to lead when heated?
Decomposed to produce PbO and oxygen gas!
What happens to gases as they are heated or cooled?
they tend to vibrate
How does entropy change in gas reactions?
Reactions that increase the moles of gas will increase in entropy.
