Question

Factors affecting the rate of diffusion is/are

K SUNKANNA · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
	**Primary Concept**: Factors Affecting Diffusion Rate
	**Related Topics**: Partial Pressure, Concentration Gradient, Fick's Law
	**Prerequisites**: Basic knowledge of diffusion
## SOLUTION PATHWAY
**Given Information**:
	List of factors: Pressure gradient, Solubility of gases, Thickness of membranes
**Method & Steps**:
	1. Recall the factors that influence the rate of diffusion.
		Reasoning: Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. This process is affected by several factors.
	2. Evaluate each listed factor.
		Working: Pressure gradient drives diffusion; solubility affects how easily a substance diffuses through a medium; membrane thickness influences the distance a substance needs to travel.
	3. Conclude that all the given factors influence the rate of diffusion.
		Result: Therefore, the correct answer is 'All of these'.
 ## OPTION ANALYSIS
[A] :x: Pressure gradient is a factor, but not the only one.
[B] :x: Solubility of gases is a factor, but not the only one.
[C] :x: Thickness of membranes is a factor, but not the only one.
[D] ✓: All the given options are factors affecting diffusion. 
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Considering only concentration gradient: Remember that other factors like pressure, solubility, and membrane thickness also influence diffusion.
	**Quick Tips**:
		1. Think of Fick's Law: Fick's Law (though not explicitly asked) can help you recall the factors influencing diffusion (rate is proportional to pressure gradient and inversely proportional to membrane thickness).
