Multiple Choice
Consider the reaction
Ni(s) + 4CO(g)
Ni(CO) 4(g)
At 30?C and PCO = 1 atm,Ni reacts with CO(g) To form Ni(CO) 4(g) .At 200?C,Ni(CO) 4(g) Decomposes to Ni(s) And CO(g) .This means
A) adding an inert gas like argon favors the forward reaction.
B) the activation energy for the forward reaction is greater than for the reverse reaction.
C) the forward reaction is endothermic.
D) K at 30?C is greater than K at 200?C.
E) a decrease in pressure favors the forward reaction.
