A reaction is performed at two different temperatures, 200 K and 450 K. The rate constant is determined at each temp, and these are shown below. At temperature = 200 K: k 200 k = 1.7 times 10^-3 M/s At temperature = 450 K k 450 k = 2.4 times 10^-2 M/s Circle T if the statement is TRUE and F if it is FALSE (or not necessarily true). Explain each choice. Your explanation is 90% of the point value. T F The reaction at 200 K is more endothermic than at 450 K T F The reaction is faster at 450 K than at 200 K T F the reaction has a greater energy' of activation at 450 K than at 200 K T F the reaction has a larger equilibrium constant at 200 K than at 450 K.
