Solution Steps

Step 1: Understanding Le Chatelier's Principle

Le Chatelier's principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change and re-establish equilibrium. However, it does not directly affect the equilibrium constant \( K \).

Step 2: Analyzing the Effect of Concentration Change

The equilibrium constant \( K \) is defined for a given reaction at a specific temperature and is independent of the concentrations of reactants or products. Changing the concentration of reactants or products will shift the position of equilibrium but will not change the value of \( K \).

Step 3: Conclusion on Equilibrium Constant

Since the equilibrium constant \( K \) is only affected by temperature changes and not by changes in concentration, the value of \( K \) remains the same when the concentration of reactants is doubled.

Final Answer

The value of the equilibrium constant \( K \) remains the same. \\(\boxed{K \text{ remains the same}}\\)

Checks and Balances The system of checks and balances is a cornerstone of the U.S. Constitution. The president, Congress, and the Supreme Court have unique constitutional procedures to check and balance the powers of the other branches. A good example of checks and balances at work occurred when Franklin D. Roosevelt was president. From 1935 to 1936, the U.S. Supreme Court struck down eight programs providing much-needed progressive reforms. Because the president strongly believed in these programs, he acted against the Court. Roosevelt pushed for legislation that would have increased the number of Supreme Court justices from nine to 15 . This would have allowed Roosevelt to nominate six justices. The number of justices had been changed six times since 1789, so the move was not without precedent. Despite strong public approval of President Roosevelt and of his New Deal reforms, the Judicial Procedures Reform Bill of 1937 failed. Critics said Roosevelt wanted to "pack" the Court with justices who would agree with him, thereby evading the Court's check on the executive branch of government. Roosevelt was a Democrat, but even lawmakers in his political party disapproved of the bill. When the chairman of the House Judiciary Committee, Democrat Hatton W. Sumners, announced that he opposed the plan, it was dead. Which sentence from the passage expresses a bias of the author? A. "A good example of checks and balances at work occurred when Franklin D.
