The equilibrium constant Kc for C(s) + CO2(g) ⇌ 2CO(g) is 1.9 at 1000 K and 0.133 at 298 K.
a.) If excess C is allowed to react with 25.0 g of CO2 in a 5.00 L vessel at 1000 K, how many grams of CO are produced? Express your answer using two significant figures. (the answers are not 32 or 28)
b.) How many grams of C are consumed? Express your answer using two significant figures.
c.) If a smaller vessel is used for the reaction, will the yield of CO be greater or smaller?
d.) Is the reaction endothermic or exothermic?
