Answer
Explanation:
Step1: Identify the reaction type
The reaction $12.6\ kJ+H_{2(g)} + I_{2(g)}\rightleftarrows2HI_{(g)}$ is endothermic as heat is on the reactant - side.
Step2: Apply Le - Chatelier's principle for temperature change
When the temperature is increased in an endothermic reaction, the equilibrium shifts to the right to absorb the added heat.
Step3: Analyze the effect on reactants and products
When the equilibrium shifts to the right, the concentration of reactants ($H_2$ and $I_2$) decreases and the concentration of the product ($HI$) increases.
Answer:
B. right, decrease, decrease, increase
