Acid is not any single substance but a class of substances. There are many different types of acid. They can be solids (such as citric acid) liquids (such as acetic acid), or gasses (such as hydrochloric acid) in their pure forms. An acidic solution is a liquid as it consists of an acid dissolved in water.
Acetic acid is a liquid at r.m.
Pure hydrochloric acid is a liquid in the room temperature and pressure.

A physical reaction is when no new substances are formed, there is a change of state eg ice melting to a liquid. A chemical change is when the reaction forms a new substance. eg gas bubbles. An acid reaction can be both. You need to look at the reaction taking place, look for change of state (physical) or any colour change or gas bubbles (chemical).
Liquid, because it's an acid.
