Which of the following statements about displacement reaction is correct?
Answer Details
A displacement reaction is a type of chemical reaction where an element or a group of atoms of a molecule is replaced by another element or group of atoms. The correct statement about a displacement reaction is that a more electropositive element displaces a less electropositive one. This is because an element with higher electropositivity has a greater tendency to lose electrons and form positive ions, making it more reactive. Therefore, it can easily displace a less electropositive element from its compound by forming a new compound with it. The position of elements in the reactivity series plays a crucial role in determining the outcome of a displacement reaction. The higher an element is in the reactivity series, the more likely it is to displace a lower element. Finally, displacement reactions can occur at any point during the reaction, and they do not require the reaction to be at equilibrium.
