Someone i need ! in the equilibrium system below, which of the following changes would cause the equilibrium position to shift to the right? co(g) + 3h2 (g) two arrows stacked on top of each other. the top arrow points to the right. the bottom arrow points to the left. ch4 (g) + h2o (g) delta h = -206 kj/mol (2 points) decreasing the concentration of carbon monoxide (co) increasing the volume of the reaction system decreasing the concentration of hydrogen gas (h2) lowering the temperature of the reaction
