In this paper, we investigate the propagation of chaos for solutions to the Liouville equation derived from the Linear-Formation particle model. By imposing certain conditions, we derive the rate of convergence between the k-tensor product \(f_{t}^{\otimes k}\) of the solution to be Linear-Formation kinetic equation and the k-marginal f N,k t of the solution to the Liouville equation corresponding to the Linear-Formation particle model. Specifically, the following estimate holds in terms of p-Wasserstein (1 ⩽ p < ∞) distance \(W^p_p(f_{t}^{\otimes k},f_{N,k}^{t}) \leqslant C_{1} {{k}\over {N^{\min(p/2,1)}}}\left(1+t^{p}\right){\rm e}^{C_{2}t}, \quad 1\leqslant k\leqslant N.\)
