### Question on Standard States of SubstancesIn this question, you are asked to determine which of the following substances is **not** in its standard state at 25°C.#### Question:Which of the following substances is not in its standard state at 25°C?#### Options:- A) H₂(g)- B) H₂O(l)- C) Pb(l)- D) Fe(s)#### Explanation:- **H₂(g):** Hydrogen gas (H₂) exists as a gas in its standard state at 25°C.- **H₂O(l):** Water (H₂O) exists as a liquid in its standard state at 25°C.- **Pb(l):** Lead (Pb) exists as a solid (Pb(s)) in its standard state at 25°C, not as a liquid.- **Fe(s):** Iron (Fe) exists as a solid in its standard state at 25°C.Therefore, the correct answer is **C) Pb(l)**, as lead is not in its standard state (solid) at 25°C when it is in liquid form.
