Question

The rate of oxidation of oxalic acid by acidified potassium permanganate is shown in the given graph. <img class="img-fluid question-image" alt="Question" src="https://cdn.tardigrade.in/q/nta/c-dhmwobdelcum.png" /> 5H2C2O4+2KMnO4+3H2SO4 arrow 2MnSO4+K2SO4+10CO2+8H2O The type of catalyst shown by such reaction is (A) heterogeneous catalysis (B) induced catalysis (C) auto-catalysis (D) negative catalysis

Tardigrade Admin · Accepted Answer

In these reactions, one of the products formed (.MnSO4.) acts as auto catalyst and thus accelerate the rate of reaction.

Q. The rate of oxidation of oxalic acid by acidified potassium permanganate is shown in the given graph.

$5 H_{2} C_{2} O_{4} + 2 K M n O_{4} + 3 H_{2} S O_{4} \to 2 M n S O_{4} + K_{2} S O_{4} + 10 C O_{2} + 8 H_{2} O$

The type of catalyst shown by such reaction is

heterogeneous catalysis

induced catalysis

auto-catalysis

negative catalysis

In these reactions, one of the products formed $(M n S O_{4})$ acts as auto catalyst and thus accelerate the rate of reaction.
