Achemical reaction has a δh of -2764 kj. this indicates that the chemical reaction that took place was a) endothermic. b) exothermic. c) neutralization. d) solvation.

B. Exothermic.

Exothermic reactions have a negative delta h.

Salvation and neutralization can both have positive and negative delta h's.

Hope I helped!

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.
