Q. For P block hydrides thermal stability is inverse to molar mass
Identify trend: Identify the trend in thermal stability for P block hydrides. Thermal stability decreases as molar mass increases.
Analyze relationship: Analyze the relationship.As the molar mass of the hydrides increases, the molecules become larger and more complex, which might affect their stability.
Conclude relationship: Conclude the relationship.The thermal stability of P block hydrides is inversely proportional to their molar mass.
