The rate of reaction when 0. 4g of zinc trioxocarbonate (IV) reacted with dilute hydrochloric acid, zin chloride was produced and carbon (IV) oxide evolved if the reaction took 2minute is 0.0016 mol/min
The rate of reaction is the time taken for product molecules to appear or the time taken for reactant molecule to be converted and the rate of reaction = mole of product formed/time taken
And the equation of the reaction is
ZnCO₃ + 2HCl → ZnCl₂ + H₂O + CO₂
And the molar mass of zinc carbonate = 125.39 = 8g/mol
Mole of zinc carbonate converted = 0.4/125.38
Time taken = 2 min
Rate of reaction = 0.0032/2
Rate of reaction = 0.0016 mol/min
