Question

a. How does a catalyst affect the activation energy?

b. Why is pure oxygen used in respiratory distress?

Short answer

a. A catalyst's capability is to lower the activation energy so that a larger proportion of the particles have adequate energy to respond.

b. The expansion in the quantity of oxygen atoms in the lungs expands the rate at which oxygen consolidates with hemoglobin. The expanded pace of oxygenation implies that the patient can inhale without any problem.

Step-by-step solution

Part(a) Step 1: Given information  

We need to find out how does a catalyst affect the activation energy of a reaction.

Part(a) Step 2: Explanation 

The pace of a chemical reaction is inextricably linked to its activation energy. The higher the activation energy, in particular, the slower the chemical reaction will be. A catalyst's capability is to lower the activation energy so that a larger proportion of the particles have adequate energy to respond. By positioning the interacting particles so that effective collisions are practically assured and responding with the reactants to frame a structure that takes less energy to shape the product, a catalyst can minimize the activation energy for a reaction.

Part(b) Step 1: Given information  

We need to find out why is pure oxygen used in respiratory distress .

Part(b) Step 2: Explanation 

To function effectively, your body requires oxygen. Your lungs get oxygen from the air you breath. Oxygen enters your circulation from your lungs and goes to your organs and biological tissues.

Certain diseases can cause dangerously low blood oxygen levels. If your blood oxygen level is low, you may feel gasping for air, tired, or confused.

A breathing mix having a greater oxygen content than the ambient air may be administered to a patient with breathing issues. As the number of oxygen molecules in the lungs rises, the rate at which oxygen combines with haemoglobin increases. The patient can breathe in more freely due to the enhanced rate of blood oxygenation.
