Question

For a spontaneous biochemical reaction which is associated with a zero change in entropy (ΔS=0) a. ΔH=0 b. ΔH>0 c. ΔH<0d. ΔH=K eq e. ΔH=T

Answer 1

For a spontaneous biochemical reaction with a zero change in entropy (
`\displaystyle\Delta S=0`), the relationship between enthalpy (
`\displaystyle\Delta H`) and temperature (
`\displaystyle T`) can be described by the equation
`\displaystyle\Delta H=T\Delta S`.

However, since
`\displaystyle\Delta S` is equal to zero in this case, the equation simplifies to
`\displaystyle\Delta H=0`. Therefore, the correct option is:

a.
`\displaystyle\Delta H=0`
