Question

For a reaction, \( A + B \rightleftharpoons 2C \), \( 1.0 \) mole of \( A \), \( 1.5 \) mole of \( B \) and \( 0.5 \) mole of \( C \) were taken in a \( 1\,L \) vessel. At equilibrium, the concentration of \( C \) was \( 1.0\,\text{mol L}^{-1} \). The equilibrium constant for the reaction is \( x/15 \). The value of \( x \) is:

• A. 32
• B. 22
• C. 18
• D. 16

Hint:

For equilibrium problems, make an ICE table and use stoichiometric coefficients carefully to calculate equilibrium concentrations.

Answer 1

The Correct Option is D
