Which of the following is responsible for depletion of ozone layer in upper strata of the atmosphere — Qualitative and Quantitative Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Carbon dioxide (CO2) is a key greenhouse gas that absorbs infrared radiation re-emitted by the Earth's surface and traps heat in the atmosphere. Step 2: An increase in the concentration of CO2 intensifies this greenhouse effect, leading to a rise in global average temperatures. Step 3: This phenomenon is known as global warming, which corresponds to option (b).
