For the Reaction a + 3B $\rarr$ 2C, the Rate of Disappearance of B Given by

question 80

Multiple Choice

For the reaction A + 3B $\rarr$ 2C, the rate of disappearance of B given by ( $\Delta$ [B]/ $\Delta$ t) may also be expressed as

• A)(\(\Delta\)[B]/\(\Delta\)t) = - (1/3)\(\Delta\)[A]/\(\Delta\)t.
• B)(\(\Delta\)[B]/\(\Delta\)t) = - 3\(\Delta\)[A]/\(\Delta\)t.
• C)(\(\Delta\)[B]/\(\Delta\)t) = 3 \(\Delta\)[A]/\(\Delta\)t.
• D)(\(\Delta\)[B]/\(\Delta\)t) = (1/3) \(\Delta\)[A]/\(\Delta\)t.
• E)(\(\Delta\)[B]/\(\Delta\)t) = -\(\Delta\)[A]/\(\Delta\)t.
