A system is changed from an initial state to by a process such that `DeltaH = q`. If the change from the initial state to the final state were made by a different path, would `DeltaH` and q be the same as that for the first path?

To solve the question, we need to analyze the relationship between enthalpy change (ΔH) and heat (q) when a system transitions from an initial state to a final state via different paths. ### Step-by-Step Solution: 1. **Understanding Enthalpy Change (ΔH)**: - Enthalpy (H) is a state function, which means that its value depends only on the initial and final states of the system, not on the path taken to get there. - Therefore, the change in enthalpy (ΔH) when moving from an initial state (A) to a final state (B) is given by: \[ ...

  • A system is changed from initial state to final state in such a manner that DeltaH=q . If the same change from initial state to final state were made by different path , which of the following statements are correct?

    A
    `DeltaH` remains the same
    B
    `DeltaH` will depends upon the path
    C
    Heat exchange will be same if the path is isobaric
    D
    Heat ecchanged q will be different if the path is non-iosbric.

  • In a change from state A to state B

    A
    `q` depends only on the initial and final state
    B
    `w` depends only on the initial and final state
    C
    `DeltaE` depends only on the initial and final state
    D
    `DeltaE` depends upon the path adopted by `A` to change into `B`.

  • Changes in a system from an initial state to the final state were made by a different manner that DeltaH remains same but q changes because

    A
    `DeltaH` is a path function and q is astate function
    B
    `DeltaH` is a state function and q is a path function
    C
    Both `DeltaH` andq are state function
    D
    Both `DeltaH` and q are path function
