    According to kinetic theory, the reactant molecules are assumed to be hard spheres and reaction is postulated to occur when molecules collide with each other. Pre-exponential factor in the expression obtained during collision theory is known as

    A)  collision diameter          

    B)  collision frequency    

    C)  collision energy
