1,The average rate of the following reaction at a certain temperature is 2.93×10-2 M/min. Calculate the value for the rate of change of [Na3PO4], in M/min, at this temperature. Report your answer to three significant figures in scientific notation. 3Ba(NO3)2(aq) + 2Na3PO4(aq) → Ba3(PO4)2(s) + 6NaNO3(aq) 2,If the intial concentration of Ba(NO3)2 is 0.351 M and the initial concentration of Na3PO4 is 0.414 M, determine the concentration of Na3PO4 (in M) after 147 seconds. Assume the volume of the solution does not change and report your answer to three significant figures in scientific notation.
