The Equilibrium Constant,K_p,equals 3.40 for the Isomerization Reaction

question 4

Multiple Choice

The equilibrium constant,K_p,equals 3.40 for the isomerization reaction:
Cis-2-butene ⇌ trans-2-butene
If a flask initially contains 0.250 bar of cis-2-butene and 0.165 bar of trans-2-butene,what is the equilibrium pressure of each gas?

• A)P(cis-2-butene)= 0.0485 bar and P(trans-2-butene)= 0.165 bar
• B)P(cis-2-butene)= 0.0458 bar and P(trans-2-butene)= 0.156 bar
• C)P(cis-2-butene)= 0.0735 bar and P(trans-2-butene)= 0.250 bar
• D)P(cis-2-butene)= 0.0943 bar and P(trans-2-butene)= 0.321 bar

Piaget's Stages

A theory by Jean Piaget that describes four stages of cognitive development in children: Sensorimotor, Preoperational, Concrete Operational, and Formal Operational stages.

Sensorimotor

Relates to the first stage of Jean Piaget’s theory of cognitive development, where infants learn through interacting with the world through sensory experiences and motor activities.
