Assertion The reaction of zinc with hydrochloric acid goes to completion in an open container. Reason Hydrogen gas is evolved from the reaction of zinc and hydrochloric acid.

1. Statement 1 and Statement 2 are correct and Statement 2 is the correct explanation of Statement
2. Both the Statement 1 and Statement 2 are correct and Statement 2 is not the correct explanation of Statement 1.
3. statement 1 is correct but Statement 2 is not correct
4. Statement 1 is not correct but Statement 2 is correct

Correct answer: Statement 1 and Statement 2 are correct and Statement 2 is the correct explanation of Statement

Solution

Zinc reacts with hydrochloric acid to form zinc chloride and hydrogen gas. In an open container, the hydrogen escapes, so the reaction is driven forward and effectively goes to completion. Thus both statements are true, and the gas evolution explains why the reaction proceeds to completion.
