condition where Q is zero and therefore the reaction must go forward to make some C. The RICE table will help. Here is the table the way you should create it. R : A + B 2C I : 0.1 0.1 0 Processing math: 100% 0.1M+x Loading [Contrib]/a11y/accessibility­menu.js
2/27/2017 LE13 RICE Tables: Sp17 ­ CH302 Sutcliffe (50385) 0.1M –x Correct! Yes. The final line in a RICE table shows the equilibrium amounts which is the initial amount with any changes (+ or –). In this case, the initial amount of substance A was 0.1M and the change to substance A was –x so the final line reads 0.1M–x. 0.1M–2x 0.1M+2x 0.1M 2.5 / 2.5 pts Question 2 Fill in the blanks in the table below. R. 2A + 2B C + D I. 3.5 M [ Select ] 0 M 0.1 M C. – 2x – 2x + x + x E. [ Select ] 0.9M – 2x x 0.1M + x Correct!
3/5 Answer 2: Answer 3: Yes. As you can determine by looking at the final row ("E" for equilibrium) the starting concentration of the substance B is 0.9M. + x Correct! Yes. The coefficient in front of D is one just like the coefficient in front of C. So if C changes by a + x amount, then D would change by the same amount. So to be clear if C had changed by + 6.75y then D would also change by the same amount! So be careful to observe the set up of the problem and balance the coefficients correctly throughout the RICE table. 3.5M – 2x Correct! Loading [Contrib]/a11y/accessibility­menu.js
