The rate of a certain reaction is given by the following rate law: rate = k[H2][I2] Use this information to answer the questions below. What is the reaction order in H?? What is the reaction order in I?? What is overall reaction order? At a certain concentration of H2 and I2, the initial rate of reaction is 56.0 M/s. What would the initial rate of the reaction be if the concentration of H2 were halved? Be sure your answer has the correct number of significant digits. The rate of the reaction is measured to be 8.0 x 10<sup>4</sup> M/s when [H2] = 0.32 M and [I2] = 0.54 M. Calculate the value of the rate constant. Be sure your answer has the correct number of significant digits.

The only way to input data into the program through the keyboard and printout result on screen. 3. A string is a sequence of only zero characters. 4. Strings in C++ are enclosed in single quotation marks. 5. In a string, the position of the first character is 1, the position of the second character is 2, and so on. 6. The assignment operator can be used with the string type. 7. The length of a string is the number of characters in the string. 8. The header file fstream contains the definitions of ifstream and ofstream. 9. For file I/O, you must use the statement #include <fstream> to include the header file. 10. To close a file as indicated by the ifstream variable inFile, you use the Statement inFile.close().
