Data Based Question

Today, we discussed the answers to the Data - Based Questions. 

*Note: The labelling of the graph is incorrect. 'Yield of Ammonia' is switched with 'Pressure'. In simple words, 'Yield of Ammonia' will be on the y-axis, and 'Pressure' on the x-axis.

Here are the answers to the questions:

1) The temperature 200 degree Celsius achieves the highest yield of ammonia.

2) As the pressure increases, the yield of ammonia increases as well.

3) The reasons are that:

• expensive to maintain
• more cost effective to produce lesser yield at faster rate

4) As the pressure increases, the amount of ammonia will increase However, it is expensive to build and operate a plant that can withstand such high pressures. So, a compressed pressure is used of 200atm.

5) If pressure is increased, then system will shift to the side with fewer moles of gas. So if pressure is increased, then system will shift to the right side, that is the product side. And since, it is shifting right, forward reaction is flavored.

This is our learning from May 13th.

Take away from this class: We learnt that Le Chatelier's Principle cannot be always followed because we need to make more ammonia.
