A chemistry student wants to find out the effect on the equilibrium position when the volume of a reaction mixture is changed. They have an equilibrium mixture of hydrogen and iodine gases forming hydrogen iodide gas according to the equation:$$H_2 (g) + I_2 (g) \leftrightharpoons 2HI (g)$$At 298 K, the equilibrium constant for this reaction is 54.3. Initially, the reaction mixture contains 0.5 moles of hydrogen gas, 0.5 moles of iodine gas, and 0 moles of hydrogen iodide gas in a container of volume 2L. If the volume is reduced to 1L while maintaining the temperature at 298 K, what wi
