Q. Which of the following is not a property of spontaneous process?
Therefore, flow of heat from a cold body to a hot body is a non-spontaneous process as it requires external work as per Clausius.
Q. What does it mean for a chemical reaction to be spontaneous?
In chemistry, a spontaneous processes is one that occurs without the addition of external energy. A spontaneous process may take place quickly or slowly, because spontaneity is not related to kinetics or reaction rate.
Q. Which is the most important factor in determining the state of a substance quizlet?
Discuss why temperature is the most important factor in determining the state of a substance.
Q. Which statement about spontaneous and non spontaneous process is correct?
Terms in this set (37) Which statement about spontaneous and nonspontaneous processes is correct? Spontaneous processes are favored by a decrease in mc003-1. jpgH, but nonspontaneous reactions are favored by an increase in mc003-2.
Q. Which label shows the overall enthalpy change?
Answer: The label that shows the overall enthalpy change is the label D.
Q. What is enthalpy change on a graph?
An enthalpy diagram plots information about a chemical reaction such as the starting energy level, how much energy needs to be added to activate the reaction, and the ending energy. An enthalpy diagram is graphed with the enthalpy on the y-axis and the time, or reaction progress, on the x-axis.
Q. How do you solve enthalpy problems?
Once you have m, the mass of your reactants, s, the specific heat of your product, and ∆T, the temperature change from your reaction, you are prepared to find the enthalpy of reaction. Simply plug your values into the formula ∆H = m x s x ∆T and multiply to solve. Your answer will be in the unit of energy Joules (J).
