1.	In a reaction `A+B hArr C+D` , the initial concentrations of A and B were 0.9 mol `dm^(-3)` each. At equilibrim the concentration of D was found to be 0.6 mol `dm^(-3)`. What is the value of equilibruim constant for the reaction ?A. 8B. 4C. 9D. 3
Answer» Correct Answer - B `{:(,A,+,B,hArr, C,+,D),("Initial conc.",0.9M,,0.9M,,-,,-),("At equilibrium",0.3M,,0.3M,,0.6M,,0.6M):}` `K=([C][D])/([A][B])=(0.6xx0.6)/(0.3xx0.3)=4`
