Question

For a liquid phase reaction ,2A+B→R. Take CRo=0 and CAo=CBo., if the conversation of A is 80% then what is the conversion of B?_____________________

A)80%

B)40%

C)60%

D)50%

Answer 1

2A + B → R

Initial C_A0 = C_B0 0

Final concentration for A compound C_A0 - 0.8xC_A0 = 0.2C_A0

2 moles of A reacts with 1 mole of B

Final concentration for B compound C_B0 - 0.4xC_B0 = 0.6C_B0

B) 40%
