Asample of radium-226 decays to form radon-222. a solution of agno3 and nacl reacts to form agcl and nano3. how would an increase in the amounts of reactants affect these reaction rates?

An increase in the amount of radium-226 will increase the reaction rate as radioactive decay follows first order kinetics.

An increase in the amount of   and NaCl will increase the reaction rate as the reaction follows first order kinetics with respect to and first order with respect to NaCl.

If the amount of radium is doubled , the rate of the reaction also doubles.

If only the amount of is doubled , the rate of the reaction also doubles. If only the amount of NaCl is doubled , the rate of the reaction doubles. lf the concentration of   and NaCl both are doubled, the reaction rate becomes 4 times.
