Question

What will be order of reaction and rate constant for a chemical change having t_50% v/s log conc. (1) curve as -

• A. 0, 1
• B. 1, 1
• C. 2, 2
• D. 3, 1

Answer 1

Answer: (A)

0, 1

Answer 2

For a reaction, t_1/2 × a^1–n = K(.a)^1–n

log t_1/2 = (1 – n) log a + log k

(y = mx + c)

1 – n = tan 45° Ž n = 0
