Video transcript

Hello everyone today. We have the following problem identified the molecular charity of each elementary reaction shown below. So we can recall that there's three types of molecular charity. There's uni molecular by molecular And lastly we have try molecular As the name suggests. Uni molecular involves one molecule that rearranges itself By molecular involves two molecules colliding And try molecular. As the name suggests, it involves three molecules colliding. And so if we look at our first choice here, we see that we have one molecule plus another molecule colliding to make a product. And so our one is going to be by molecular. If you look at our second answer choice or our second question here we see we have three molecules colliding. So this is going to be in tune with try molecular. And lastly we see that for our third question we only have one molecule and this one molecule is going to be undergoing a unique molecular molecular charity. And so these are our answers for our questions overall. I hope this helped. And until next time.
