For the reaction A + B 2C the equilibrium constant is 100 at 298 K. If each of the three species starts at an initial concentration of 1 M, the equilibrium concentration of C equals x * 10⁻¹ M. Find the nearest integer value of x.

Question

For the reaction A + B <=> 2C the equilibrium constant is 100 at 298 K. If each of the three species starts at an initial concentration of 1 M, the equilibrium concentration of C equals x * 10⁻¹ M. Find the nearest integer value of x.

Accepted Answer

25. Solving the equilibrium expression gives extent p = 0.75, so [C] = 1 + 2(0.75) = 2.5 M = 25 * 10⁻¹ M, hence x = 25.
