Any help is appreciated

Nitrosyl chloride (NOCI) decomposes into nitrogen oxide and chloride gases. (a) Balance the reaction below by filling in the correct coefficients NOCI(g) NO(g) + Cl2(g) (b) Complete the rate equation for the reaction by filling in the correct factor to be multiplied to the rate of change in the concentration of NOCI. (Input a decimal number if dividing) A[NOCI rate = At (C) The concentration of NOCI drops from 0.580 M to 0.238 M in 8.00 minutes. What is the average rate of reaction over this time interval? mol/L-min
