ANS:D - Vanderwall adsorption is also called chemisorption.

The wrong statement is: "Vanderwall adsorption is also called chemisorption." Van der Waals adsorption, also known as physisorption, involves the adsorption of molecules onto a surface through weak van der Waals forces, such as London dispersion forces or dipole-dipole interactions. It does not involve chemical bonds forming between the adsorbate and the adsorbent, as is the case in chemisorption. So, the correct statement would be: "Van der Waals adsorption is also called physisorption."

ANS:B - velocity gradient is zero at the solid surface.

When a fluid flows over a solid surface, the statement that best describes the situation is: velocity is not zero at the solid surface. Here’s why:

• Velocity Profile: In fluid dynamics, when a fluid flows over a solid surface (such as flow in a pipe or over a plate), the velocity of the fluid at the solid surface is not zero. The fluid adheres to the surface due to viscosity and exhibits a phenomenon known as the "no-slip condition," where the fluid velocity at the surface matches the velocity of the surface itself.
• No-Slip Condition: According to the no-slip condition, the fluid directly at the solid surface moves with the same velocity as the surface, assuming the surface is stationary or moving at a different velocity than the fluid. This means the velocity of the fluid is not zero at the solid surface; rather, it matches the surface velocity due to frictional effects.
• Velocity Gradient: There is a velocity gradient within the fluid layer adjacent to the solid surface. This gradient starts from zero at the surface (due to the no-slip condition) and increases further into the fluid.
• Resistance and Layers: The resistance between the solid surface and the fluid is actually higher compared to the resistance between fluid layers themselves, especially near the surface where viscosity plays a significant role.

ANS:D - Amit Shah

ANS:B - both temperature & pressure in the former is more than that

Comparing the sulfate process with the sulfite process, we find that both temperature & pressure in the former is more than that. Comparing the sulfate process with the sulfite process, we find that both temperature and pressure in the former (sulfate process) is more than that due to the following reasons:

Sulfate Process:

1. Higher Temperatures: The sulfate process typically operates at higher temperatures, often around 140-160 °C (284-320 °F). This elevated temperature helps in effectively breaking down wood chips and extracting lignin, making the process more efficient.
2. Higher Pressures: It usually requires higher pressures, often in the range of 5-10 bar (approximately 72-145 psi), to ensure proper reaction kinetics and maximize the yield of the desired products.

Sulfite Process:

1. Lower Temperatures: In contrast, the sulfite process operates at lower temperatures, typically around 100-130 °C (212-266 °F). This lower temperature is sufficient for the reactions involved but limits the efficiency of lignin removal compared to the sulfate process.
2. Lower Pressures: The pressures in the sulfite process are also generally lower, often atmospheric to slightly above, making it less energy-intensive than the sulfate process.

Summary of Comparisons:

Implications:

• Efficiency: The higher temperature and pressure in the sulfate process lead to better yields and more complete breakdown of lignocellulosic materials, making it a preferred method in many industrial applications.
• Product Quality: The sulfate process often results in higher-quality pulp, which is crucial for producing stronger and more durable paper products.
