S.L. Miller an American scientist created electric discharge experiment in a closed flask containing `CH_(4),H_(2),NH_(3)` and water vapour at what temperature?

Options

A. `400^(@)C`
B. `800^(@)C`
C. `200^(@)C`
D. `1000^(@)C`

Answer

To answer the question regarding the temperature at which S.L. Miller conducted his electric discharge experiment, follow these steps:

1. **Identify the Experiment**: Understand that S.L. Miller performed an experiment to simulate the conditions of primitive Earth to investigate the spontaneous formation of organic compounds.

2. **Components of the Experiment**: Recognize that the closed flask contained gases such as methane (CH₄), hydrogen (H₂), ammonia (NH₃), and water vapor.

3. **Temperature Setting**: Recall that the experiment required a specific temperature to mimic the conditions of early Earth.

4. **Determine the Temperature**: From the information provided, it is noted that the temperature at which Miller conducted his experiment was around 800 degrees Celsius.

5. **Select the Correct Option**: Based on the temperature identified, the correct answer to the question is 800 degrees Celsius.

Thus, the answer is: **800 degrees Celsius**.
