the reaction shifts left or toward the reactants when hydrogen is removed. which substance increases in concentration during the shift? h₂(g) + cl₂(g) ⇌ 2hcl(g) + 184.6 j
Answer
Answer:
$Cl_2$
Explanation:
Step1: Understand Le - Chatelier's principle
When a system at equilibrium is disturbed, it shifts to counteract the change.
Step2: Analyze the given change
Hydrogen ($H_2$) is removed. The reaction $H_2(g)+Cl_2(g)\rightleftharpoons 2HCl(g)$ shifts left.
Step3: Determine concentration change
As the reaction shifts left, more $Cl_2$ is formed from the decomposition of $HCl$, so $Cl_2$ concentration increases.
