3.Which statement correctly explains a difference between white and red phosphorus? (1 point)
White phosphorus has less chemical potential energy than red phosphorus.
.
White phosphorus has more chemical potential energy than red phosphorus.
White phosphorus has a higher activation energy than red phosphorus.
White phosphorus has a lower activation energy than red phosphorus.
4.How can the chemical potential energy in an endothermic reaction best be described?(1 point)
Reactants have higher chemical potential energy than products.
Products and reactants have the same chemical potential energy.
Product and reactant chemical potential energy varies in different environments.
Products have higher chemical potential energy than reactants.
5.How are activation energy and reaction rate most likely related?(1 point)
Higher activation energy results in a faster reaction rate.
Higher activation energy results in a slower reaction rate.
A faster reaction rate results in higher activation energy.
A faster reaction rate results in lower activation energy.

To echo PsyDAG, I see no choices you picked; therefore, I assume quick check in your mind means you give me the answers and I'll have no need to check anything. I have a better idea. You give us your choices and we'll see if they are correct.
1.energy input needed to break bonds of reactants
2.energy stored in chemical bonds
3.White phosphorus has a lower activation energy than red phosphorus
4.Products have higher chemical potential energy than reactants.
5.Higher activation energy results in a slower reaction rate.
