Consider the reaction 2A(9) = 2B(9) + C(9) For this reaction at 25.0C, the value of Kis 8.868. Calculate K for the following reaction at 25.0C. 2B(g) + C(q) = 2A(9) A. 0.11 B. 8,87 C. None of these D. 17.74 E. 10.00 Consider the reaction: 2A(g) = 2B(g) + C(g) For this reaction at 25.0C, the value of Kis 1.2 x 103 At 50.0C the value of Kis 0.34 Indicate if heat is released or absorbed in this reaction (write the reaction including heat). Is the reaction exothermic or endothermic? Select one: a. heat + 2A(9) = 2B(9) + C(q) exothermic b. heat + 2A(9) = 2B(9) + C(9) endothermic C. 2A(g) = 2B(9) + C(q) + heat exothermic d. 2A(g) = 2B(9) + C(g) + heat endothermic e.
