Place instant pot rack on top of chicken. In a oven proof pan (sized to fit instant pot) pour rice and equal parts water into it and stir. Place on top of rack.
Close lid of instant pot, place valve into the sealed position. Cook on high pressure for 6 minutes. After time is up, Allow 10 minutes of natural release, then flip the valve to release any remaining steam. Open lid.
