two drugs are injected intot he same thigh muscle. Drug A is body temperature (37 C) and has a molecular weight of $150 \mathrm{~g} / \mathrm{mol}$. Drug B has been in the refridgerator (5 C) and has a molecular weight of $600 \mathrm{~g} / \mathrm{mol}$. Predict which drug will diffuse into the blood more rapidly. Explain your reasoning.

Question

Accepted Answer

∻Answer∻ ⚹ Drug A will diffuse into the blood more rapidly. ⚹ ∻Solution∻ ‖ a ⋮ Temperature: Drug A is at body temperature (37°C), while Drug B is refrigerated (5°C). Higher temperatures increase the kinetic energy of molecules, leading to faster diffusion rates. ‖‖ b ⋮ Molecular Weight: Drug A has a molecular weight of $150 \mathrm{~g} / \mathrm{mol}$, whereas Drug B has a molecular weight of $600 \mathrm{~g} / \mathrm{mol}$. Lower molecular weight allows for faster diffusion through tissues. ‖ ∻Key Concept∻ ⚹ Diffusion Rate ⚹ ∻Explanation∻ ⚹ Drug A, being at a higher temperature and having a lower molecular weight, will diffuse more rapidly into the blood compared to Drug B. Higher temperature increases molecular movement, and lower molecular weight facilitates easier passage through the muscle tissue. ⚹◊How does molecular weight affect the rate of diffusion into the bloodstream?⍭ Generate me a similar question◊
