Titration of sodium carbonate and nitric acid 25cm³ of sodium carbonate require a certain volume of nitric acid of conc. 0.13M for complete neutralization

They are all solids.

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.

It is a product

The higher the temperature, the increased rate constant for a reaction.(positive linear association)
