Expert Answer

Step 1

The temperature of -15.90C is equivalent to 257.25 K and the temperature of 1.90C is equivalent to 275.05 K. The absorbed heat of 90.0 kJ/mol is equivalent to 90.0×103 J/mol. Heat absorbed at constant pressure is defined as the enthalpy change.

Step 2

On the basis of given facts, Kc at 275.05 K is calculated as shown in equation (1) where 254.25 K is the initial temperature, 275.05 K is the final temperature,...
