MCQ
Select the correct statement regardings sulphur :-
  • A
    At high temperature it's paramagnetic
  • B
    $S-S$ has less bond energy than $O-O$ bond
  • C
    Sulphur exist in $S_8$ form and it has cage like structure.
  • Size of sulphur is greater than oxygen so, it (sulphur) has less electron a affinity than oxygen.

Answer

Correct option: D.
Size of sulphur is greater than oxygen so, it (sulphur) has less electron a affinity than oxygen.

Consider the reaction $A \rightleftharpoons B$ at $1000 K$. At time $t ^{\prime}$, the temperature of the system was increased to $2000 K$ and the system was allowed to reach equilibrium. Throughout this experiment the partial pressure of $A$ was maintained at $1$ bar. Given below is the plot of the partial pressure of B with time. What is the ratio of the standard Gibbs energy of the reaction at $1000 K$ to that at $2000 K$ ?
