When the chemical reaction shown below is at equilibrium, if the volume is reduced, in what direction would the reaction shift? C3H8(g) + 5 O2(g) ⇌ 3 CO2(g) + 4 H2O(l) ΔH° = −2220 kJ a. To the left b. To the right c. No change Would it shift to the left? Or right since volume works inversely of pressure

» What color did you observe after adding the 3M H2SO, solution? 4) What color did you observe after adding the IM NaOH solution? Assume that the dynamic equilibrium represented in the equation in I is present in the original solution you placed in the test tube. Based on LeChatelier's Principle, as stated above on page one, you will interpret the observations made in 2, above: (Note that H SO, produces H+ in solution.) a) When sulfuric acid was added,...

Question 17 (1 point) With the onset of the 2007-2008 Great Recession, the Fed, led by Fed Chairman Ben Bernanke (2006- 2014), lowered its target interest rate (the federal funds rate) to a range of 0.00-0.25 percent. This was done with 7 rate cuts during 2008, after several in 2007. Consider the market for money illustrated in the figure below. Assume the market initially (just prior to Great Recession) is in equilibrium at point A. Describe the effects the Fed's...

MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answer the question 1) Which of the following statements is FALSE? A) When K<< 1, the reverse reaction is favored and the forward reaction does not proceed to a great extent. B) K>> implies that the reaction is very fast at producing products. When K>>> 1, the forward reaction is favored and essentially goes to completion. D) When K-1, neither the forward or reverse reaction is strongly favored,...
