Q. Reduction potential of four elements $P,\ Q,\ R,\ S$ is $- 2.90,\ + 0.34,\ + 1.20$ and $- 0.76$. Reactivity decreases in the order
A) $P > Q > R > S$
B) $S > R > Q > P$
C) $P > S > Q > R$
D) $Q > S > R > P$
Explanation
(c)
Reducing power, $ie,$ the tendency to lose electrons increases as the reduction potential decreases
