Is the lattice energy of a compound positive or negative?
The lattice energy of a compound is always negative.
Can binding energy be negative?
No, binding energy cannot be negative. Binding energy is always a positive quantity that represents the energy required to hold a system together. If the binding energy were negative, it would imply that the system is in an unstable state.
Can the change in kinetic energy be negative?
Yes, the change in kinetic energy can be negative if the object's speed decreases, resulting in a decrease in kinetic energy.
Is the lattice energy always negative?
No, the lattice energy can be positive, negative, or zero, depending on the specific compounds involved.
Is it possible for the change in kinetic energy to be negative?
Yes, it is possible for the change in kinetic energy to be negative. This occurs when an object loses kinetic energy, such as when it slows down or comes to a stop.
Why is the enthalpy change of combustion always negative?
The enthalpy change of combustion is always negative because it involves the breaking of bonds in the reactants, which requires energy input, and the formation of new bonds in the products, which releases energy. The energy released during bond formation is greater than the energy required for bond breaking, resulting in a net release of energy, hence the negative value.

Will a process with a large negative g always proceed rapidly?
No, a process with a large negative g does not always proceed rapidly. The rate of a reaction is determined by various factors, not just the change in free energy.
Is potential energy in k-shell is negative then why?
bcoz the energy of bound system is always negative
When will Gibbs free energy always be negative?
Gibbs free energy (ΔG) will always be negative for a spontaneous process occurring at constant temperature and pressure. This typically occurs when the change in enthalpy (ΔH) is negative (exothermic reactions) and the change in entropy (ΔS) is positive, leading to a favorable increase in disorder. Additionally, even if ΔH is positive, a sufficiently large positive change in entropy can also result in a negative ΔG at high temperatures, according to the equation ΔG = ΔH - TΔS.

When is a reaction always spontaneous according to Gibbs free energy equation?
A reaction is always spontaneous when the change in Gibbs free energy (ΔG) is negative (ΔG < 0). This occurs when the system's enthalpy change (ΔH) is negative and the entropy change (ΔS) is positive, or when the temperature is sufficiently low to make the term TΔS (where T is temperature) less significant compared to ΔH. In summary, spontaneous reactions can be identified by a negative ΔG value, indicating that they can occur without external input.
Why is the hydration of an ion always negative?
The hydration of an ion is negative because energy is released when water molecules surround and stabilize the ion. This release of energy is favorable and results in a negative enthalpy change. The hydration process is exothermic, meaning it releases heat.
According to the Gibbs free energy equation G H - TS when is a reaction always spontaneous?
when H is negative and S is positive
