How does the Gibbs free energy predict spontaneity?
It tells if the reaction will process spontaneously or not
Is it true that non spontaneous process never happens in universe?
non spontaneous process happen in the universe but energy has to be provided to them . the free energy change of such processes are positive . the amount of temperature has to be increased to carry out such reactions
Is the Uniform mixing of bromine vapor and nitrogen gas a spontaneous or non spontaneous reaction?
spontaneous
What kind of enthalpy change favors a spontaneous reaction?
An exothermic reaction is a chemical reaction that releases energy in the form of heat. It favors a negative enthalpy change.
Is salt dissolves in water spontaneous or not spontaneous?
Spontneous
Why the spontaneous radiation incoherent?
Because the moment of emission the polarization and the propagation direction , the direction of the wave vector is random. Spontaneous emission causes incoherent radiation.
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 kind of reaction occurs when the entropy change of an endothermic reaction is negative?
The reaction is exothermic
Agent that causes change in the activity of a structure?
systems
Under what circumstances can an object move in a circular path without being accelerated?
It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.
What causes a spaceshuttle to change in velocity by change in direction?
A change in velocity constitutes a change in direction because velocity includes direction.
How If a reaction occurs at 293 K that has a change in enthalpy of plus 125 kJ and a change in entropy of plus 35 J K then is the reaction spontaneous If so why If not why not?
A process will be spontaneous when the change in Gibbs free energy is negative.The change in Gibbs free energy can be calculated from the equation:G2 - G1 = H2 - H1 - T(S2 - S1)whereG is Gibbs free energyH is EnthalpyT is absolute temperature (when T is given in Kelvin or Rankine it is an absolute temperature)S is EntropyIn this caseH2 - H1 = 125 kJT = 293 KS2 - S1 = 35 J/K = 0.035 kJ/Kso doing the math you getG2 - G1 = 125 - 293(0.35) = 22.45 > 0 so the process is not spontaneous in the direction where enthalpy change and entropy change are being measured. The reverse process would be spontaneous.
How can you make an asteroid change direction?
Asteroids dont change direction
What is to change direction?
acceleration in a direction that is not parallel to the direction you are moving
Drivers require to signal of change a direction of direction for at least...?
Drivers require to signal of change a direction of direction for at least how many feet?
Does a hurricane ever change its direction of rotation?
No. A hurricane will not change its direction of rotation.
How is a change in an object's direction related to the applied force?
In order to change direction, the applied force (represented as a Vector) must change DIRECTION. A change in magnitude of the Force is not necessary.
