For a certain reaction `X`rarr`Y` the value of `DeltaH` and `DeltaS` are `50.50KJ mol^(-1)` and `100.03JK^(-1)` respectively. The temperature at which `DeltaG=0` isA. `505^(@)C`B. `232^(@)C`C. `252^(@)C`D. `450^(@)C` |
Answer» Correct Answer - A Given, `DeltaH=50.50KJ mol^(-1)` `DeltaS=100JK^(-1)=100xx10^(-3)=0.1KJK^(-1)` `:.` From `DeltaG=DeltaH-TDeltaS` `implies 0=DeltaH-TDeltaS` `implies T=(DeltaH)/(DeltaS)=(50.50)/(0.1)=505K` `:. T=505-273=232^(@)C` |
