What can be said about a reaction with triangle H 620 kJmol and triangle S -046 kJ(mol.K)?
it is never spontaneous
What is -7h equals 35?
h = -5 -7 * -5 = 35 A negative times a negative equals a positive.

The product of two integers is an integer?
Well, it depends on if you are talking negative or positive. Think of it this way: -Negative = hate (H) -Positive = love (L) love to hate = hate hate to love = hate love to love = love hate to hate= love Get it? * * * * * All that is valid but totally irrelevant. The simple answer is: Yes, the product of two integers is always an integer.
A chemical reaction has a positive H value and a positive S value Under what conditions is the reaction spontaneous?
the reaction is always spontaneous :) youre welcome =D i just took this on apex, the correct answer is the reaction is spontaneous only at high temperatures.
What can be said about a reaction with H 620 kJmol and S -0.46 kJ molK?
it can never be spontanious
According to the Gibbs free energy equation G H - TS when is a reaction always spontaneous?
when H is negative and S is positive
How is temperature affect the spontaneity of a reaction with positive H and S?
∆G = ∆H - T∆S and ∆G has to be negative for the reaction to be spontaneous. So, ultimately the effect of temperature will depend on the value of ∆H. If ∆H is negative, and ∆S is positive, then temperature won't matter, and reaction will be spontaneous. If ∆H is positive, and ∆S is positive, then a high temperature will favor spontaneity. If ∆H is negative and ∆S is negative, then a low temperature will favor spontaneity. So, the answer to your question is the higher the temperature the more likely the reaction will occur spontaneously.
Are chemical reactions always spontaneous when H is negative and S is negative?
No, when H and S are both negative, the reaction will only be spontaneous below a certain temperature
What determine whether a reaction took place?
Use the following equation: delta G = delta H - T*deltaS. A reaction is spontaneous if delta G is negative. A reaction will always be spontaneous (under any temperature) only if the change in enthalpy (delta H) is negative and the change in entropy (delta S) is positive. If this is not the case, the reaction will only be spontaneous (negative delta G) for a range of temperatures (or could be always non-spontaneous)
What conditions will a low temperature make a reaction spontaneous?
if H and S are both negative
What conditions will a low temperature male a reaction spontaneous?
If H and S are both negative
How will temperature affect the spontaneity of a reaction positive delta h and delta s?
∆G = ∆H - T∆S and for it to be spontaneous, ∆G should be negative. If both ∆H and ∆S are positive, in order to get a negative ∆H, the temperature needs to be elevated in order to make the ∆S term greater than the ∆H term. So, I guess the answer would be "the higher the temperature, the more likely will be the spontaneity of the reaction."
Under what conditions will a low temperature make a reaction spontaneous?
if H and S are both negative
How will temperature affect the spontaneity of reaction with positive H and S?
A high temperature will make it spontaneous.
How will the temperature affect the spontaneity of a reaction with positive h and s?
A high temperature will make it spontaneous.
