How many times will the reaction rate N2 + 3H2 = 2NH3 increase if the hydrogen concentration is increased by 2 times and nitrogen by 4 times.
The rate will be directly proportional to the concentration of nitrogen and hydrogen, taken in powers of the corresponding coefficients in the equation.
V = k * C (H2) * C (H2) ^ 3,
N2 + 3H2 = 2NH3
When the hydrogen concentration is increased by 2 times, the speed will increase by 8 times (2 ^ 3 = 8). When the nitrogen concentration is increased by 4 times, the speed will increase by 4 times. If we increase the concentration of both substances according to the condition, then the rate of the chemical reaction will increase 8 * 4 = 32 times.
