How does entropy change in gas reactions?
Reactions that increase the moles of gas will increase in entropy.
Which would represent an increase in entropy?
thawing
What describes the entropy change of gas reaction?
if there is an increase in the number of gas molecules , then ^S > 0
Which of the following describes the entropy change of a gas reaction?
If there is an increase in the number of gas molecules, then S > 0.
What changes a liquid or a solid to a gas?
usually a change in temperature.... OR PRESSURE Which all mean a change in entropy of the system
How do you predict delta s?
delta s (change in entropy) is positive when.... -you go from a solid to a liquid -you go from a liquid to a gas -when you go from a solid to a gas -when there are more mols of products than mols of reactant the change in entropy is negative when the reverse of the above happens
Is it possible for entropy to be negative and For entropy change to be negative and For entropy production to be negative?
Assuming you mean can entropy be reduced; the answer is yes. Only in an open system such as our planet. The universe is a closed systems. The entropy of the universe cannot be reduced. Chemical changes can reduced entropy in an open system. When gas turns into a liquid or when a liquid turns into a solid; entropy is reduced.
Which phase has the highest entropy?
Gas
What is the definition of entropy?
The entropy of the gas was too high. It means the degree of randomness in gas was very large.
Why sublime substance change directly from solid to gas on heating?
Because the entropy is negative making it spontaneous.
What happens to the entropy of gas as it is heated?
In a closed system the entropy is constant.
What is true about entropy?
Entropy is not change. Entropy is disorder.
