If I have connected analog sensor with I2C based ADC controller is it possible to send the I2C based data converted serially and send to arduino or not ?
If yes then what will be the best way to do ?

I wanted to interface analog sensor with Arduino nano using ADC, What is the best way to interface it using serial communication?
How can I adjust the baud-rate of serial communication (suppose if I wanted to send the data at 200Kbps only) ?
Any lead on this will be very helpful
