If the gas can get hot, yes, it's called an explosive. Zap, and boom.
Some serve in airbags for instance. These gases don't get so hot. But the reactants are astonishingly dangerous for a car.
Reversibly, that would be much more difficult. At least, you don't hope an effect stronger than the electricity you put in, do you? Energy conservation.
Just heating a gas with the electricity has decent efficiency. Not good, but better than piezoelectricity, magnetoelasticity and so on.
