Consider the following two first order reactions occurring at 298 K with same initial concentration of A :

(1) A $$\to$$ B; rate constant, k = 0.693 min$$-$$1

(2) A $$\to$$ C; half-life, t1/2 = 0.693 min

Choose the correct option.
A
Reaction (1) is faster than reaction (2)
B
Reaction (1) is slower than reaction (2)
C
Both reactions proceed at the same rate.
D
Since two different products are formed, rates cannot be compared.
