Question

Hello I am doing a Chemistry Lab and I do not understand this lab.

I have to watch this video

Part 1 https://www.youtube.com/watch?v=2qlHHPCkCKE&feature=youtu.be *Only 1 minute long

Part 2 https://www.youtube.com/watch?v=7XeWFX3fnTI&feature=youtu.be​ * Only 2 minute long

Can someone help me answer these questions with the sub questions? I am confused. And explain please

--How does the slope change with time for a given species?

--Is the slope the same for all species?

--What is the sign of the slope for the reactants?

--What is the sign of the slope for the product?

Answer 1

The videos show the inversion vs the cost in other terms. This means that as A+B are mixed in order to produce C

A+B are going to decrease their concentration and C is going to increase its concentration.

A. the slope is nothe the same for all species. As the slope of A and B decrease, the C slope increase.

B. the sign of the slope for reactants is negative, which means they are decreasing but after a time they become constants.

C. the sign of the slope of the products is positive which means in increasing its concentration but after a time it becomes constant.
