Both. One side of the equatioo loses energy and the other side gains it.
positive to a negative
If you connect the positive and the negative end of a battery directly with a cable, (1) you'll get dangerously high currents, and (2) the battery will quickly run out of energy. The battery itself might also get damaged, due to the high currents.
Unless they are kept apart, they will annihilate each other with a release of energy.
They are a useful energy sourceThey cause no pollution when producing energyThey are expensive to build
That's a difference in electrical potential, not potential energy.It's described in units of "volts".
G = -nFE Therefore, G will be negative when EMF is positive.
The reaction in which energy is being released, and the overall energy change (enthalpy) is negative.
In the electrostatic forces between the positive atomic nuclei and the negative atomic electrons.
If the ∆H is positive and the ∆S is positive, then the reaction is entropy driven. If the ∆H is negative and the ∆S is negative, then the reaction is enthalpy driven. If ∆H is positive and ∆S is negative, then the reaction is driven by neither of these. If ∆H is negative and ∆S is positive, then the reaction is driven by both of these.
The substances which increase the rate of a chemical reaction are called a Positive Catalyst whereas The substances which decrease the rate of a chemical reaction are called Negative Catalyst. Positive Catalyst decreases the Activation energy of reactant molecules whereas negative catalyst increases the Activation energy of the reactant molecules. Positive Catalyst is also called the Promoter whereas negative catalyst is also called Inhibitor.
exothermic heat is negativeA different opinion:Heat itself cannot be negative. An exothermic reaction is a chemical reaction wherein a substance gives up heat. Since the substance is giving up energy in the form of heat, the enthalpy change of the substance is negative.
positive to a negative
An endergonic reaction is a chemical reaction in which the standard change in free energy is positive.
A positive catalyst is a catalyst which speeds up the rate of a chemical reaction by lowering its activation energy. A negative catalysts slows the rate of a chemical reaction or makes it less likely to occur.
when H is negative and S is positive
