Free energy is the minimum energy necessary for product to form?
False, the minimum reaction energy needed for a reaction to form or take place is called the activation energy.
Why there is a cutoff requency in the photoelectric effect?
In any circumstance where a threshold of energy is required to free an electron from a bound state, an incoming photon must have at least that energy to do the job. The energy of a photon is proportional to the frequency of the light, so the minimum energy corresponds to a minimum frequency of the light, or maximum wavelength necessary to free an electron. This observation was a major step in the development of radiation theory (Einstein).
What equation is used to calculate the free energy change a reaction?
Delta G (written triangle G) = Delta H -T Delta S
Calculate the energy of a meteoric impact?
Energy = Mass * Velocity squared. It all depends on the mass and the velocity. The MINIMUM velocity of a meteoric impact is about 7 miles per second, the speed at which an item would fall from free space. Things coming in from the outer solar system could be going several times faster, and a particle falling from deep space could be going upwards of 50 miles per second.
What is the free energy for C2O4-2?
the free energy would be water that floats in the air, because it takes up energy while floating around.
What is threshold frequency?
Threshold frequency (fo) is minimum frequency at which electrons are ejected from a metal.
Free energy is the minimum energy necessary for product to form?
False, the minimum reaction energy needed for a reaction to form or take place is called the activation energy.
How to calculate helmholtz free energy for ideal gas?
F=U-TS where F is the Free energy, U is energy, T temperature and S entropy
Minimum gibbs free energy is NOT attained by a semipermeable membrane. True or false?

Can you go from activation energy from free energy?
Did you mean to ask "Can you go from activation energy tofree energy"?The answer might be found in looking at the definition of the coefficient of performance (COP), which states something like this:COP is the ratio of work or useful output (possibly free energy) to the amount of work or energy input (activation energy).If the COP is greater than one, then more energy is being produced than is required to produce it. One might argue that there is no such thing as free energy if you have to work for it.We are surrounded by free energy. Is the energy produced by a water wheel free? Is the energy produced by a wind turbine free? Is the electricity produced by a solar collector free? The energy is free for the collecting, but the method for collecting it has a cost of some kind.Check wikipedia for "trompe". There is a theory that the Giza pyramid has an underground structure that was designed as a trompe.

If a positive charge is free to move but is at rest in an electric field E what will it do?
Accelerate in the same direction as E.

Why free electrons on metal surface are emitted on energy supply?
In atoms and molecules that make up all materials, electrons are bound by attractive forces, magnitude of which depend on the electronic structure of the material. In the case of metals, this binding energy is rather small and if we supply an energy equal to this binding energy (also called, work function) the electrons can be set free.
