【单选题】反应3R(g)+Q(g)【图片】2T(g)的Kc=2.25,在平衡时T的浓度是3.00mol·dm-3,R的浓度是2.00mol·dm-3,则Q的浓度是
A.
0.500mol·dm -3
B.
0.667mol·dm -3
C.
1.50mol·dm -3
D.
2.00mol·dm -3
【简答题】反应A+B→C,速率方程为v=kc(A)c(B)。当A、B的起始浓度都是0.20mol·dm -3 时,反应速率为8×10 -4 mol·dm -3 ·s -1 ;如A、B的起始浓度均为0.60mol·dm -3 时,其反应速率将是(    )。 (A) 8×10 -4 (B) 1.6×10 -3 (C) 2.4×10 -3 (D) 7.2×10 -3
