Webdraw tangents to curves and use the slope of the tangent as a measure of the rate of the reaction calculate the gradient of a tangent to a curve as a measure of the rate of a reaction at a specific time. Setting the scene The rate of a chemical reaction tells you how fast reactants are turned into products. You WebThe general formula for the reaction rate, based on the coefficients, can be written as: aA + bB → cC + dD So, for our reaction, the reaction rate would be: H2(g) + Cl2(g) → 2HCl(g) custom lego star wars sites
