The diagram shows the course of the reaction for a chemical reaction. With and without catalyst. R stands for reactant and p stands for product. Which statement or statements are true? 1. H4 and H5 together make up the total enthalpy change of the reaction.❌?
2. The reaction is endothermic.❌
3. The presence of catalyst allows a larger amount to be formed a larger amount of the products.❌?
4. H1 <0 ✅
(EXOTERM h1 <0
(Endotherm h1> 0)
5. The activation energy is higher for the catalyzed reaction ❌?
6. The reaction is exothermic
7. H1 is the total enthalpy change ✅?
Activation energy non-catalyzed reaction = H3? ✅

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.

explanation:

idk i’m struggling too

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42
