A) \[N{{a}_{2}}C{{O}_{3}}\]
B) \[NaOH\]
C) alcohol
D) \[Pt\]
Correct Answer: C
Solution :
Pure hydrogen peroxide is unstable and decomposes on heating \[{{H}_{2}}{{O}_{2}}+{{H}_{2}}{{O}_{2}}\xrightarrow[{}]{{}}2{{H}_{2}}O+{{O}_{2}}\] \[\Delta H=-196kJ\] The decomposition of\[{{H}_{2}}{{O}_{2}}\]is retarded (ie, stability is increased) by adding a small amount of acid, glycerol, alcohol or acetanilide (-ve catalyst).You need to login to perform this action.
