moles of solute/mass of solvent(kg) 


moles of solute/liters of solution 

freezing point depression formula 

delta T = i x Kf x m i = vant hoff factor Kf = freezing point depression constant m = molality 


Rate = k [A]^m [B]^n k = rate constant [A] & [B] = molar concentration of reactants m & n = order of the reactants 


the sum of the orders = m+n 


= (mass of solute/total mass of solution)x 100 






k = Ae^(Ea/RT) R = 8.31447 J/(mol * K) 

Arrhenius equation when comparing two points 

ln (k2/k1) = (Ea/R){(1/T1) – (1/T2)} R = 8.31447 J/(mol * K) 

y = mx + b for Arrhenius Equation 

ln k = (Ea/R)(1/T) + ln A y = m x + b
