The black scholes equation is a boundary value problem which requires a terminal value condition (i.e. a known value at at known expiry date). As an American option can be excersised at any given time it must be modeled by a free boundary problem, which requires further analysis beyond the standard black scholes equations. You can however use Black scholes on other options eg. Asian

The black scholes model price options based on a set of mathematical parameters known as the "greeks" which covers the variables that influence options prices. However, this is only a theoretical model because it cannot take into consideration the actual demand and supply condition of specific options in the market. Actual demand and supply most often move the price of an option away from its theoretical value.

How is the worth of an option determined?
The worth of an option depends on a few major components:1. The price of the underlying stock in relation to its strike price. i.e Options Moneyness2. Implied volatility3. Time to Expiration4. Risk Free Interest Rate5. DividendsOut of these 5 components, the first 3 items have the most influence on the price of an option. The Black-Scholes Options Pricing model uses these components in the pricing of stock options as well.
There is a violation in an option price given the black scholes opm how would you arbitrage if i a call option is overpriced ii the call is underpriced iii a put option were overpriced?
First of all, an option is considered overpriced or underpriced with an arbitrage opportunity only when it is overpriced or underpriced in relation to its synthetic equal, not when it is overpriced or underpriced in relation to the black-scholes model. The black-scholes model only provides an estimated theoretical price that cannot fully and accurately price in the prevailing implied volatility.Once an option is overpriced or underpriced in relation to its synthetic equal by a margin that is big enough to overcome multiple bid/ask spread loss and commissions loss on multuple legs, all you have to do is to perform a conversion or reversal in order to reap an arbitrage.

How to value an option accurately in the financial markets?
To accurately value an option in the financial markets, investors use mathematical models like the Black-Scholes model.
