A reaction is found to be second order with respect to reactant A. What would be the effect on the rate if the concentration of A were doubled? The rate would double The concentration of A has no effect on the rate The rate would decrease by half The rate would quadruple

Give the characteristic of a zero order reaction having only one reactant. The rate of the reaction is not proportional to the concentration of the reactant. The rate of the reaction is proportional to the square of the concentration of the reactant. The rate of the reaction is proportional to the square root of the concentration of the reactant. The rate of the reaction is proportional to the natural logarithm of the concentration of the reactant. The rate of the reaction is directly proportional to the concentration of the reactant.

Radioactive decay of unstable atomic nuclei is at first order process. The half-life for the radioactive decay of 14C is 5730 years. An archeological sample contained wood that had 87% of the 14C found in living trees. How old is the archaeological sample (in years)?

What does the order of a reactant indicate as it relates to the rate of the reaction?

For a certain first order reaction, it takes 449 seconds for the concentration of reactant to decrease from 2.9 M to 0.97 M. What is the half-life of the reaction in seconds? Round your answer to the nearest second.
