What is true for two pieces of iron at the same temperature? a. heat flows from the larger object to the smaller object. b. the total kinetic energy of their particles is equal. c. heat flows from the object with higher potential energy to the object with lower potential energy. d. the average kinetic energy of their particles is the same.

D. The average kinetic energy of their particles is the same.

If I’m correct, it would be D :)

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
