Asked by Bob

Write the equation for the decomposition of HI, knowing that the reaction requires 9.4 kj/mol of hydrogen forming. If 100.0 kj of energy are added, how many grams of iodine will form.
Answered by DrBob222
2HI ==> H2 + I2
9.4 kJ energy produces 2 g H2 AND 2*127 = 253.8 g I2. So 100 kJ will produce what?
2g H2 x 100/9.4 = ? g H2.
253.8 g I2 x 100/9.4 = ? g I2.
