The halogenoalkanes, being covalently bonded, give no precipitate of silver halide, but as the reaction proceeds and halide ions are produced, a precipitate of silver halide gradually appears agcl = white precipitate, agbr = off-white precipitate, and agi forms a pale yellow precipitate. Graph 1: a graph of time against amount of reactants used u p my hypothesis was accurate the larger the surface area of the calcium carbonate, the higher the rate of reaction and the smaller the surface area of the calcium carbonate, the the beginning, which shows that its reaction is quicker.
This shows that the rate of reaction is getting less5 22 mol dm-3 44 minutes the gradient is negative because the concentration is decreasing notice how the gradient gets less as the reaction proceeds5 10 03 x 10-2 mol dm-3 min-1 concentration of reactant concentration v for the following.
