According to the Gibbs Free Energy equation, some reactions only occur spontaneously at very high temperatures. At high temperatures, the reaction becomes spontaneous if both the entropy as well as the enthalpy are positive.
Changes in Enthalpy, Entropy, as well as Free Energy, Remember that such temperature in the Gibbs free energy equation would be the Kelvin temperature, and as such, it can only be positive. The reaction will constantly be spontaneous at any and all temperatures when H is negative and S is positive, and G's sign is going to be negative.
If a reaction happens without any outside influence, it has been said to as spontaneous. This reaction can release energy and only takes place in the specific circumstances.
Therefore, At high temperatures, the reaction becomes spontaneous if both the entropy as well as the enthalpy are positive.

The original concentration of the acid solution is 6.175 10^-4 mol / L.
<u>Explanation:</u>
Concentration is the ratio of solute in a solution to either solvent or total solution. It is expressed in terms of mass per unit volume
HBr + NaOH -----> NaBr + H2O
There is a 1:1 equivalence with acid and base.
Moles of NaOH = 72.90 10^-3 0.25
= 0.0182 mol.
[ HBr ] = moles of base / volume of a solution
= 0.0182 / 29.47
= 6.175 10^-4 mol / L.
Speed = distance / time
I think the answer would be "divided by"
What is this, atoms, moles, grams?
Convert it into what?
I believe the answer is E. uranium
