Expert Answer:

Elementary reactions have same value of order and molecularity.
 
Elementary reaction is chemical reaction in which one or more reactants racts directly to form product in a single step with single transition state.
 
Example:
 
straight A space space space plus space space space straight B space space space rightwards arrow space space space Products

Rate space equation space colon space open square brackets straight A close square brackets to the power of 1 space end exponent open square brackets straight B close square brackets to the power of 1

Order space of space reaction space is space sum space the space of space coefficients space of space rate space equation comma

therefore space Order space of space reaction space equals 2
space space space space space space space space space space space space space Molecularity space equals space 2
