Chapter 14, Problem 14.41QP

For the reaction

${\text{H}}_2(g)+{\text{CO}}_2(g)\stackrel{}{\rightleftharpoons }{\text{H}}_2\text{O(}g\text{)}+\text{CO(}g\text{)}$

at 700°C, K_c = 0.534. Calculate the number of moles of H₂ that are present at equilibrium if a mixture of 0.300 mole of CO and 0.300 mole of H₂O is heated to 700°C in a 10.0-L container.
