MCQ
For a chemical reaction $A+B \rightleftharpoons C+D$ $\left(\Delta_{r} H^{0}=80 \,k J\right.$ $mol\,^{-1}$ ) the entropy change $\Delta_{r} S^{0}$ depends on the temperature $T$ (in $K$ ) as $\left(\Delta_{ r } S ^{0}=2 T \left(\, J \,K ^{-1}\, mol ^{-1}\right)\right.$
Minimum temperature at which it will become spontaneous is ..... $K.$(Integer)
- A$50$
- B$250$
- ✓$200$
- D$150$
