$2MnO_4^ - + 5{C_2}O_4^{2 - } + 16{H^ + } \to 2M{n^{2 + }} + 10C{O_2} + 8{H_2}O$
Here $20\,ml$ of $0.1\,M$ $KMn{O_4}$ is equivalent to
$X_2 + Y_2 \rightarrow 2XY,$ is given below :
$(i)\,\, X_2 \rightarrow X + X\, (fast)$
$(ii)\,\,X + Y_2 \rightleftharpoons XY + Y\, (slow)$
$(iii)\,\,X + Y \rightarrow XY\, (fast)$
The overall order of the reaction will be
