A student sets up the electrolysis experiment following the instructions in Experiment 20. When the student's back is turned, a gremlin raises the current to a value of 0.2 amp, which is twice the value of 0.1 amp that the student initially set. Which of the following statements are true about the rate of hydrogen gas formation? a. The rate of gas formation will be approximately twice as a fast
b. The rate of hydrogen gas formation will be approximately four times greater
c. The rate of gas formation will be approximately 1/4 as fast
d. The rate of gas formation will be approximately one-half as fast
e. The rate of gas formation will remain the same
