The values of Kw as a function of temperature are as follows: Is the autoionization of water exothermic or endothermic? Choose the right variant. exothermic endothermic it depends on pressure it depends on temperature b What is the pH of pure water at 50°C? 6.631 From a plot of ln(Kw) versus 1/T (using the Kelvin scale), estimate Kw at 37°C, which is the normal physiological temperature.

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.
