Hydrogen reacts with iodine to form hydrogen iodide: H2[g] + 12[g] = 2H1[g] The forward reaction is endothermic. The reaction reaches equilibrium. Which of the
following changes in the reaction conditions will cause the position of
equilibrium to move to the right?*

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

elements make up everything, and they combine to make compounds.

the answer is c
