In a chemical equilibrium C2H6C_{2}H_{6}C2H6C_{2}H_{6}, when one mole each of the two reactants are mixed, 0.6 mole each of the products are formed. The equilibrium constant calculated is.

A

1

B

0.36

C

2.25

D

4/9

Answer

2.25

Explanation

Solution

A + B ⇌C + D

Initial 1 1 0 0

remaining at equilibrium 0.4 0.4 0.6 0.6
