What condition is G for a reaction always positive?
When H and S are both positive
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)
Does bacillus subtilis have a positive reaction for ONPG Test?
yes it have positive reaction for ONPG test
How does the entropy change in the reaction 2C3H6 (g) plus 9O (g) 6CO2(g)?
The entropy increase in this reaction.
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."
What condition is G for a reaction always positive?
When H and S are both positive
Under what conditions is G for a reaction always positive?
When H is positive and S is negative
Is free energy of cell reaction positive when emf of cell reaction is positive?
G = -nFE Therefore, G will be negative when EMF is positive.
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.
According to the Gibbs free energy equation G H - TS when is a reaction always spontaneous?
when H is negative and S is positive
What conditions make G always negative?
G is always negative when H is negative and S is positive.
What conditions make delta G always positive?
G is always positive when enthalpy increases and entropy decreases.
What conditions make G positive?
G is always positive when enthalpy increases and entropy decreases.

For which of reaction listed below will gibbs free energy always be positive?
Guys watch out the question, if your question end with positive then the answer will be An endothermic reaction that decreases in entropy. If the question end with negative then its An exothermic reaction that increases in entropy--APEX hope this help
How do you tell which is greater a negative number or a positive number?
a positive number is always greater than a negative number
What is the reaction of positive and positive?
A positive
