Explanation:
Hello,
In this case, the undergoing chemical reaction is:
Thus, Kp for this reaction is computed based on the given molar fractions and the total pressure at equilibrium, as shown below:
Now, by using the Van't Hoff equation one computes the equilibrium constant at 298.15K assuming the enthalpy of reaction remains constant:
Finally, the Gibbs free energy for the reaction at 298.15K is:
Best regards.
Answer:
F' = 3 N
Explanation:
Given that,
Two objects of equal mass have a force of gravity of 6 N between them.
If the mass of one is cut in half and the other stays the same such that,
m₁' = m₁ and m₂' = (m₂/2)
We need to find the new force. The gravitational force between two objects is given by :
We have, F = 6 N
New force,
So, the new force becomes 3 N.
