Problem

A graph plotted between log⁡10KC\log_{10} K_C and 1/T1/T is straight line with intercept 10 and slope equal to 0.5. Calculate: (i) pre-exponential factor A. (ii) heat of reaction at 298 K. (iii) equilibrium constant at 298 K. (iv) equilibrium constant at 800 K assuming ΔH\Delta H remains constant in between 298 K and 800 K.
