Expert Solution
Step 1: Relation between equilibrium constant Kp and Kc

Answer:

straight K subscript straight C equals straight K subscript straight P left parenthesis RT right parenthesis to the power of negative increment straight n subscript straight g end exponent

Here:

straight R equals universal space gas space constant
straight T equals Temperature space left parenthesis in space straight K right parenthesis
increment straight n subscript straight g equals change space in space number space of space gaseous space moles
