* Lab question: How can you distinguish a physical change from a chemical change?
> Format: How can you distinguish A from B?
Answer! Comparison: physical changes vs. chemical changes
Answer:1.01
Explanation:∆G(system)= ∆G(product) - ∆G(reactant)
Therefore, we have: -32 - 209.2 = -242.09 kj/mol.
Also, ∆G(system)= -RT ln kp ----{*}
R= 8.314, T= 298, kp =? , ∆G(system)= -242.09 kj/mol.
We can now substitute into equation {*}.
I.e, -242.09kj/mol= -8.314×298 ln kp
-242.09= -24477.572 ln kp
In kp= - 242.09÷ -24477.572
ln kp= 0.00989
kp= 1.0099.
~ 1.01
As electronegativity difference increases, the degree of ionic character increases.
The answer is increases.
Decreasing the surface area of the solute.
