6.3 ASSIGNMENT: Science Blog: Equilibrium (Due March 1)

ASSIGNMENT: Science Blog: Equilibrium (10 points)

This Week's Science Blog Topic: For this week's blog entry, watch the video and answer the questions that follow.

• Look at the first four collisions in the video. In collision A, two people bump into each other. In collision B, two molecules (the large one is ethene, the small one is hydrogen) bump into each other. In collision C, the same two people bump into each other; and in collision D, the same two molecules bump into each other. In collisions A and B, no reaction happens. In collisions C and D, reactions do happen. Look closely at the four collisions and give two reasons why reactions happen in cases C and D but not in cases A and B.

• Explain why the rate of the reverse reaction must be zero at the beginning of a reversible reaction. Explain why the rate of the reverse reaction increases as the reaction proceeds.

• Explain why the proportion of reactants and products at equilibrium does not have to be 50/50.

Blog Guidelines: 

• Each blog post should be at least one paragraph (3-5 sentences minimum).

• Use complete sentences, proper grammar and punctuation.

• All posts/comments must be respectful.  Vulgarity or rudeness will result in school disciplinary action.
