You still write the KCL equation at the "-" input to the opamp. The impedance to the right is just the sum of the impedances of the resistor and capacitor. Can you show us that equation and then how you would solve it to get Vo/Vi?

yeah i can do it when its standard integrating op amp circuit but when a resister ans capacitor is added(see below image) to the inverting terminal in feedback then i don't know how to form equation

Currents sum in a series circuit? Your "KCL" equation is not a KCL equation!
